Introducing the Storage Access API – Microsoft Edge Blog

Today, we’re excited to announce the “first-look” rollout of the Storage Access API in our Canary and Dev channels. For developers, this API allows them to determine whether their access to browser-based storage is restricted by a user’s privacy settings and to request storage access from users if so. This capability can be used to create graceful fallback experiences in cases when storage access may be restricted by features such as tracking prevention in Microsoft Edge. For users, this API provides greater transparency into and control over the sites that are requesting access to browser-based storage that could be used to track their behaviors across the web. This post outlines what the addition of the Storage Access API means for both developers and users.

Using the Storage Access API is as easy as updating your code to leverage the following new functions:
hasStorageAccess()
Useful to check if access to cookies and other storage exists in the current context.
Returns a promise with a boolean result indicating if storage access exists or not.

requestStorageAccess()
Requires a user gesture to invoke.
Useful to request access to storage for a single third-party context.
Returns a promise that will resolve if access is either available or granted and reject if unsuccessful.

Note: Since we are still gradually rolling out the Storage Access API, it’s possible that you may not have it enabled by default on your device. If you want to test it early, please enable the “Storage Access API” flag in edge://flags.
The usage of these new functions is best demonstrated with an example.
Example:
A social media site, contoso.social, offers sites the ability for developers to embed social media widgets as third-party content on their sites. One site where these widgets appear is www.contoso.example. To offer the ability for contoso.social users to comment on, save, or share contoso.example content with friends, contoso.social’s embedded content needs access to its own storage such as cookies or localStorage in the context of contoso.example in order to associate these actions with a visitor’s account.
Checking for Access:
contoso.social can use document.hasStorageAccess() to see if access to storage already exists and to provide an alternative user experience such as displaying a request to login or request access if not:

Requesting Access:
If no storage access is currently present, contoso.social can request access during a user gesture. As an example, the onclick handler of a login button could be tied to a request for storage access (see the “User Experience” section below) using the document.requestStorageAccess() method.

Sandboxing
The allow-storage-access-by-user-activation token can be used to enable the usage of the API when embedded content is loaded in a sandboxed iframe. In practice, both the allow-scripts and allow-same-origin tokens will also be required as well to ensure the API can be effectively used.

As a developer, we hope you will leverage the Storage Access API to create web-based experiences that will continue to be compatible even as browsers place more restrictions on third-party storage.

With the introduction of the Storage Access API, you may notice an “Allow cookies and site data?” prompt like the one below when you interact with third-party content such as social media widgets or embedded videos while browsing:

This indicates that the site whose embedded content you’re interacting with (contoso.social in the example above) currently has its storage restricted by Microsoft Edge’s privacy settings and is requesting your permission to access its storage within the context of the site you’re visiting (https://www.contoso.example in the example above). While several types of sites require storage access for legitimate scenarios such as making sure you’re signed in when you expect to be, allowing this access can allow the site requesting it track your activity on the site you’re currently visiting.
Clicking “Allow” will temporarily allow the requesting site access to its storage on the site you were visiting when the prompt appeared. This allowance will last for a 30-day period after which it will automatically expire. Clicking “Block” will prevent the requesting site from accessing its storage on the site you were visiting when the prompt appeared. If you change your mind, interacting with the third-party content a second time will cause the prompt to be displayed again, giving you the option to revisit your choice.
To give you control over any storage access requests you’ve allowed before they automatically expire, you’ll notice a new “Cookies and site data you’ve temporarily allowed” section at the bottom of the edge://settings/content/cookies page. Here, you can review and revoke the storage access requests you’ve granted in a single list:

We implemented the Storage Access API upstream so that all Chromium-based browsers could benefit from it. We are also actively participating in standardization discussions that are ongoing in the W3C Privacy Community Group to ensure that the API works uniformly across browsers. If you have any feedback on the functionality or capabilities of the API itself, please feel free to join the standardization discussions by filing an issue on GitHub. If you have any feedback on the Storage Access API as it exists in Microsoft Edge, please send us feedback using in-app feedback tool (Alt + Shift + I).
To close, we’d like to thank our friends at Apple and Mozilla for their early work on the Storage Access API and our friends at Google for helping pave the way for getting the API implemented in Chromium. We’re excited for you to try it out and to hear what you think!

Introducing an improved spellcheck experience in Microsoft Edge – Microsoft Edge Blog

Beginning with Microsoft Edge 83, we’ve introduced a new spellcheck experience for Windows users, powered by Windows Spellcheck. The feature is supported on Windows 8.1 and above.
Previously, on Windows, Microsoft Edge and other Chromium browsers used open-source proofing tools for spell checking. Moving to Windows Spellcheck has a number of benefits, including support for additional languages and dialects, a shared custom dictionary, and better support for URLs, acronyms, and email addresses.
Based on early feedback from preview users, this represents an overall improvement in the quality of spell checking in Microsoft Edge, as illustrated in the examples below.

Hunspell Spellcheck

Windows Spellcheck

How to use spellcheck in Microsoft Edge
For most users, no action is required to set up spell checking – it will automatically inherit your preferred language settings from Windows. To configure the languages that will be spellchecked, navigate to the edge://settings/languages page.

Users can install additional languages to spellcheck in Windows Settings by navigating to Time & Language -> Language and selecting Add a preferred language.

If the user has not installed the necessary language pack (or if one is not available), Microsoft Edge will fall back to the prior experience powered by Hunspell.
This feature was developed as a collaboration between Google and Microsoft engineers in the Chromium project, enabling all Chromium-based browsers to benefit from Windows Spellcheck integration. Our thanks go out to Guillaume Jenkins and Rouslan Solomakhin (Google), and Bruce Long, Luis Sanchez Padilla, and Siye Liu (Microsoft) for their collaboration on this feature.
The new spellcheck experience is now available in Microsoft Edge starting with version 83, recently released to the Stable channel. Try it out and let us know what you think!

Introducing the new surf game in Microsoft Edge – Microsoft Edge Blog

Starting with build 83.0.478.37, users can now play a surfing-themed game in the new Microsoft Edge when they’re offline or by navigating to edge://surf. The game, which has been available for Insiders since late February, is now available for everyone to play in the latest Stable channel release. Download the new Microsoft Edge here to get started surfing today!

Inspired by the classic Windows game SkiFree, the surf game challenges players to ride through the water while avoiding islands, fellow surfers, and other obstacles. Watch out for the kraken! Players can also collect hearts to extend their lives and boosts for a burst of speed. Surf as far as possible in an endless ocean, compete for the shortest time, or zig zag through as many gates as you can in a row. With three distinct game modes, players have a variety of ways to pass the time.
To catch the wave, simply navigate to edge://surf in the address bar. If you are not connected to the internet, Microsoft Edge will also provide a handy link to the game to help you pass the time.

An early version of the surf game originally debuted in November as part of a special Easter Egg. Insiders followed a series of cryptic hints and puzzles in the run-up to Microsoft Ignite 2019 which eventually led them to unlock the hidden surf game using Collections. Upon reaching the end of the game, Insiders were treated to the world’s first look at the new icon for Microsoft Edge—two days before the official reveal.
Upon the conclusion of the Easter Egg, the number one request from Insiders was to turn the surfing game into an endless runner as the permanent “offline game” for Microsoft Edge. The team took this feedback to heart and has spent the last few months polishing edge://surf and adding new gameplay features and improvements, including support for accessibility features like high contrast, screen readers, and even the Xbox Adaptive Controller. Here’s a look at what’s included:
Let’s surf: Endless mode
Surf as far as you can while avoiding obstacles and the kraken. You can switch modes via the game settings menu.
Time trial mode
Reach the end of the course as fast as you can! Collect coins to help you achieve an even shorter time. The course is always the same—can you find the shortest possible route? You can switch modes via the game settings menu.
Zig zag mode
Surf through as many gates as you can in a row! Your streak will reset if you miss a gate, but you can keep playing until your lives run out. You can switch modes via the game settings menu.
Play with keyboard, mouse, touch, or gamepad
Play your way with support for keyboard, mouse, touch, and gamepads, including Xbox, PlayStation, Switch Pro, and the Xbox Adaptive Controller. The game also supports gamepad haptic feedback (rumble) for a more immersive experience. Instructions for how to play, including the controls for each input method, can be found in the game’s settings menu.
Personal high scores
Each game mode keeps a record of your high score, and you’ll see a notification every time you set a new record. You can also reset your stats from the game settings menu.

High visibility mode
High visibility mode (accessible via the game settings menu) highlights the hit boxes around objects, making it easier to identify and avoid obstacles in the water.
Reduced speed mode
For users who prefer a more relaxed pace or need extra time to pull off those surfing moves, they can enable the new reduced speed mode (accessible via the game settings menu) to slow down the speed of the game.
And much more!
The final release of edge://surf has many changes based directly on user feedback from the Easter Egg version, including an enhanced user experience, numerous gameplay improvements (such as smarter enemy logic) and bug fixes, and much more. Who knows? There might even be a few secrets just waiting to be found.
Thanks again to our incredible community that made this possible. Happy surfing!
– William Devereux, Senior Program Manager, Microsoft Edge

Everything new from Microsoft Edge at Build 2020 – Microsoft Edge Blog

Microsoft Build 2020 can be defined by a set of ‘firsts’—it’s the first Build of the new decade, the first Build that’s all-digital for 24 hours a day, and the first Build since the new Microsoft Edge launched! We’re learning a lot as we deliver Build and Microsoft Edge in new ways.
Last year at Build, we unveiled what was coming with the new Microsoft Edge. Since then we haven’t stopped innovating to build a browser that’s right for you, with world-class performance and more security, more productivity, and more value as you browse.
We’ve introduced tools to give you more control over your privacy with Tracking prevention. We’ve added new ways to be more productive with Collections. And with Give Mode, we’ve turned searching with Bing into an easy way to do something good.
As mentioned in January, we plan to upgrade all Windows 10 devices (excluding enterprise and education) to the new Microsoft Edge. Users will be able to experience all the features above when it’s delivered via a measured roll-out that you’ll see ramping up over the course of the next few weeks. If you can’t wait and want to try it now, you can download the new Microsoft Edge here.
We believe in a web that just works for everyone. As we work to deliver a great browsing experience, we remain committed to listening to developers and sharing improvements back to the open source community that makes Microsoft Edge possible. To date, we’ve made over 3,000 commits back to the Chromium open source project that make the web more enjoyable, capable, and accessible for everyone.
This year at Build, we’re sharing ongoing innovation with improved tooling and reach for web developers, new consumer integrations, and new customization options for businesses.

What’s new for web developers
A healthy web community is made possible by a vibrant developer community. Over the last few months, we’ve worked to support that community with improvements like DevTools localization in 10 new languages, which has been adopted by many of you as you develop for Microsoft Edge. Now, we’re excited to highlight new tools that empower you, the developers who make the web possible, while expanding your canvas so you can reach your customers in more ways than ever before.
WebView2 preview expands to include .NET and UWP (WinUI) development

Last year, we pushed WebView2 forward with a preview for Win32 development. WebView2 lowers the barrier for developers to maximize code reuse across platforms with a consistent web platform to host web content in their apps. We’d like to thank everyone that has engaged with us so far throughout the preview—the contributions and feedback we’ve received drive our feature roadmap and quality.
Today, we’re expanding the preview with new options for .NET and UWP (WinUI 3.0) development, enabling you to embed a Chromium-based Edge WebView in WinForms, WPF, and UWP (WinUI 3.0) applications. Check out our documentation and Getting Started guide, or simply open Visual Studio and download the WebView2 package to get started.
Improvements to the Microsoft Edge Add-ons site make searching and finding extensions easier
For many users, extensions are a key component to the web experience. We’re committed to not only making it easy for developers to bring their Chromium-based extensions into our store, but also to make it simple for users to find them. We will be making a significant update to the Microsoft Edge Add-ons site to make it more visually appealing—new categories, new search capabilities, and a new layout will get those extensions in front of customers. Expect to see this roll out starting this month!
Making PWAs feel more at home on Windows 10
Progressive Web Apps (PWAs) continue to gain momentum as a great way to deliver content in an app-like experience across platforms, powered by web standards. With the most recent versions of Microsoft Edge and Windows 10, we’re making PWAs feel even more natural and familiar alongside other Windows apps.
Today, when you install PWAs on Windows 10, they look and feel more at home on your desktop OS in important ways, launching in a standalone window and appearing in places like Start and the Taskbar for easier access. We’re working on updates to make this integration even smoother—you’ll be able to manage them from settings, use them to share (and receive shared content), and more. Check out an early preview of this Windows integration by using Windows Insider preview builds and enabling the Web Apps Identity Proxy flag in the Microsoft Edge Canary preview build.
Try out experimental web platform features with Origin Trials
We always aim to move the web forward to meet the needs of web developers. Our Origin Trials program enables developers to test drive experimental features on their websites for a set length of time. Prototypes that we haven’t enabled for the general web yet will work on your site for a selection of your visitors in Microsoft Edge, enabling you to gather and provide early feedback which can influence the final API.
Learn more and register for an Origin Trial at the new Origin Trial Developer Console today!
New features for every user
This week, we’re also introducing a few exciting new features to help you be more productive, and a new integration to help find and organize the content you want.
Collections in Microsoft Edge is getting smarter with a new Pinterest integration
Collections helps you organize, save, and share your online life by allowing you to create groups of content from around the web. Links, images, text, and notes can be saved together across multiple sites, pages, and browser sessions to help you stay organized and inspired.
Now, Collections in Microsoft Edge is collaborating with Pinterest to help you discover relevant content for your research or project. People use Collections to capture their favorite design ideas, recipes, home improvement links, and even to research their next big purchase across multiple sites. This new integration with Pinterest will help you find ideas to spark inspiration, save time, and be more productive by suggesting content related to what you have already collected. When you enable the feature, you will see Pinterest suggestions at the bottom of your collection. Clicking on a suggestion will open a board of similar, trending Pins so you can quickly find and add ideas relevant to you.
This collaboration also allows you to export your collection to Pinterest. Any saved webpages or images will then show up in a new board in your Pinterest account.

Collections will also be rolling out the ability to send to OneNote, in addition to the options to send to Excel and Word which are available today. Collections integration with Pinterest, and Send to OneNote, will appear in Insider channels within the next month. Join our Edge insider program to be one of the first people to try it.
Sidebar search provides a faster, more contextual way to look things up

Today you have the option to look up words or phrases by searching in a new tab. This can make you lose your train of thought instead of helping you get more out of what you’re reading. Sidebar search aims to improve this experience by giving you the option to see results in a pane on the side of the page. Simply highlight a word or phrase, right click, and select “search in sidebar” from the context menu. And if you’re at work and signed in with your Azure Active Directory account, you’ll even see company results! Reading a corporate strategy paper with unlinked references? Use sidebar search to help find the answer. When you’re done, you can close out of the pane or keep searching in it to look up additional information.
Expect to see this show up in Insider preview channels in the coming weeks. Become an Edge Insider to be one of the first to try it.
New features for information workers and IT Pros
Microsoft Edge is the browser for business, and today we’re announcing new features and updates to make the lives of IT managers and information workers a little bit easier. Want to try these out in your organization? Download offline installers here.
New syncing and customization options for IT professionals

If you use multiple devices while working from home, you know how important sync is. Installed extensions now sync in Microsoft Edge and a new policy even allows IT professionals to precisely manage which types of data sync for their users. The flexibility to sync individual data types means IT professionals can fit syncing to their workplace needs. For some workplaces, syncing passwords might not be allowed—now IT can manage this.
Coming soon, sync will also extend to customers whose environments are still on-premises. The transition to the cloud takes time, and your company should be able to get the most out of Microsoft Edge during that transition.
Data security gets a boost with Windows Information Protection
As many people work from home, data protection is top of mind, especially for IT professionals. Microsoft Edge now supports Windows Information Protection for Windows 10 customers which clearly separates personal and corporate data, adds extra protection for line-of-business apps, and provides audit reporting for compliance. This has been a top ask by many customers, and we’re excited to bring it to the new Microsoft Edge.
Easily move between work and personal profiles

For information workers, we’ve made improvements to help keep them in their flow throughout the workday—this is especially true for those working at home, where work and personal boundaries can easily blend. Microsoft Edge now allows users to set a default profile for any link they open, creating a consistent experience even if they’re switching between profiles throughout the day.
Microsoft Edge helps you manage your profiles even more with a feature called Automatic Profile Switching. Previously, if you’ve been using your personal account and then try to access a work link, you’d be forced to sign-in again because your personal account doesn’t have your work credentials. With the new Automatic Profile Switching feature, Microsoft Edge will detect that the link you’re trying to open needs work credentials, and then switch you to your work profile to open it. Profile switching has never been smoother.
Microsoft Search in Bing puts your work results all in one place
Bing is bringing the life-changing capability of search to the workplace, and we have an exciting update as part of this year’s Build. A comprehensive Work page will now be part of Bing’s search results pages for all Microsoft 365 customers. When signed-in to Bing with your work credentials, this page will appear right next to other familiar pages such as Images, Shopping, and News. This new results page gives you the option to view work-specific results such as files, people, internal websites, and more. If your organization uses Microsoft 365 Apps for enterprise, just sign into Bing with your work credentials and try it today. Learn more on our new website!
We hope you enjoy this new 48-hour, all-digital format as we meet you where you are around the world—we truly can’t thank you enough for joining us online for Microsoft Build 2020.
Keep innovating, keep building, and keep expecting more from the web.

Using multiple profiles at work and at home is now easier with Microsoft Edge – Microsoft Edge Blog

Our customers tell us that they like to keep their browsing data separate as they take on various roles in their lives. For people at home working from their own devices, this is particularly important.
Microsoft Edge’s “Profiles” feature is a great way to do this, whether you’re switching between work and personal browsing, juggling your job and freelancing business, or managing your tasks as an admin alongside other responsibilities.
In this post, we’ll share some improvements coming to browsing with multiple profiles in Microsoft Edge, and walk you through how to get started with this feature.
Setting up multiple profiles
To get started with multiple profiles, click the profile icon to the right of your address bar and click “Add a profile”. Then, on the consent screen that comes next, just click “Add”. Your profile is now added.
Each profile opens in a new window and gets its own desktop icon. You can pin each desktop icon independently to your Windows taskbar by right clicking on the Microsoft Edge icon.
If you’d like to roam your data across devices, you can sign into each profile with a Microsoft Account or a Work or School Account and choose to sync your data. Since browsing data is separated between profiles, each profile will sync independent of the other.

Switching between profiles
You can switch between profiles any time by clicking on the desktop icon or window associated with a profile. You can also switch using the profile flyout by clicking the profile icon or you can switch from the edge://settings/profiles page.

Getting to the right profile
We’ve heard that two things that users find challenging is getting links to open in the right profile and making sure that you don’t mistakenly open work content in your personal profile. Today, we’re excited to announce two features that we hope will make this easier:
Selecting a default profile (available in Microsoft Edge 81 and higher)
To ensure that links you open from another app open in the profile of your choice, you can now select a default profile in Microsoft Edge. To select a default profile to open external links, do the following:
Navigate to edge://settings
Select the “Multiple profile preferences” option (Note: This will only show if you have multiple profiles.)
Use the drop down menu to select which profile you’d like external links to open with.

Automatic profile switching (available in Microsoft Edge 83 and higher)
We’re also excited to announce a new feature to help you get to your work content more easily while using multiple profiles. We call it Automatic Profile Switching. If you’re a multiple profiles user, you can check it out by trying to navigate to a work site (a site authenticated with your work or school account) while in your personal profile.
When we detect this, we will prompt you to switch to your work profile to access that site without having to authenticate to it. When you choose the work profile you want to switch to, the website will simply open in your work profile.
We hope that this will help you keep your work and personal data separate and help you get to your work content more seamlessly. In case this doesn’t work for your flows, you can choose “Don’t ask me again,” and it will get out of your way.

We are excited to release this improvement for your multiple profile scenarios—give it a try and let us know how you like it! If you run into any issues or have any feedback on using multiple profiles, use the in-app feedback button (or Alt-Shift-I) and we’ll use it to make the experience better for you.
Thank you for helping us build Microsoft Edge be the best browser for you.
– Avi Vaid, Program Manager, Microsoft Edge

Update on Stable channel releases for Microsoft Edge – Microsoft Edge Blog

In light of current global circumstances, the Microsoft Edge team is pausing updates to the Stable channel for Microsoft Edge. This means that Microsoft Edge 81 will not be promoted to Stable until we resume these updates.
We are making this change to be consistent with the Chromium project, which recently announced a similar pause due to adjusted schedules, and out of a desire to minimize additional impact to web developers and organizations that are similarly impacted.
We will continue to deliver security and stability updates to Microsoft Edge 80. Preview channels (Canary, Dev, and Beta) will continue to update on their usual schedule.
As the situation evolves, we will post updates here and on our Twitter channel.

Protecting users from potentially unwanted applications in Microsoft Edge – Microsoft Edge Blog

Our customer feedback tells us that when users search for free versions of software, they often find applications with a poor reputation being installed on the machine at the same time. This pattern indicates that the user has downloaded an application which shows offers (or bundles) for potentially unwanted applications (PUA).
Potentially unwanted applications can make the user less productive, make the user’s machine less performant, and lead to a degraded Windows experience. Examples of PUA include software that creates extra advertisements, applications that mine cryptocurrency, applications that show offers for other software and applications that the AV industry considers having a poor reputation.
In the new Microsoft Edge (beginning with 80.0.338.0), we’ve introduced a new feature to prevent downloads that may contain potentially unwanted apps (PUA), by blocking those apps from downloading. This feature is off by default, but can be turned on in three easy steps:
Tap … (Settings and more) > Settings.
Choose Privacy and services.
Scroll down to Services, and then turn on Block potentially unwanted apps.

Here is what users will see when a download is blocked by the feature (Note: PUA blocking requires Microsoft Defender SmartScreen to be enabled):

To learn more about what Microsoft defines as PUA, see the criteria in our documentation.
If an app has been mislabeled as PUA, users can choose to keep it by tapping … in the bottom bar, choosing Keep, and then choosing Keep anyway in the dialog that appears.

From edge://downloads/, users can also choose Report this app as reputable, which will direct them to our feedback site. There, users can let us know that they think the app is mistakenly marked as PUA.
If you own the site or app in question, you can let us know here. Your feedback will be reviewed by our team to determine an appropriate follow up action.

Our goal is to assist users in getting the apps they want, while empowering them to maintain control over their devices and experiences.
You can learn more about how Microsoft identifies malware, unwanted software, and PUA in our security documentation.
We encourage users to always try to download software from a trusted location, such as the publisher’s website or a reputable app store, and to check reviews of the app and the reputation of the publisher before downloading.
If you are an admin or IT professional and are interested in enabling this feature on for your users, see our enterprise documentation here.
We hope you’ll try out this new feature in the new Microsoft Edge and let us know what you think! Give us your feedback by clicking the feedback link in the upper right corner of your browser or pressing Alt-Shift-I to send feedback.

New optimizations boost performance in preview builds of Microsoft Edge – Microsoft Edge Blog

Starting with Microsoft Edge build 81.0.389.0 on 64-bit Windows 10, we’ve enabled new toolchain optimizations that should provide a substantial performance improvement in general browsing workloads.We’ve measured an up to 13% performance improvement in the Speedometer 2.0 benchmark when compared to Microsoft Edge 79. Speedometer measures performance by simulating user interactions in a sample web app across a number of DOM APIs and popular JavaScript frameworks used by top sites, and is generally regarded as a good proxy for real-world performance across a number of different subsystems including the DOM, JavaScript engine, layout, and more.
We’d like your help validating these improvements in your real-world browsing as we approach our next Beta release later this month. You can try out these improvements by comparing performance in the latest Dev or Canary builds to Microsoft Edge 80 or earlier.
The details:
We measured Speedometer 2.0 in ten consecutive runs on Microsoft Edge 79, where the optimizations are not yet implemented.  The results are below.

We would love for you to try the new optimizations in Dev or Canary and let us know if you notice these improvements in  your real-world experience. Please join us on the Microsoft Edge Insider forums or Twitter to discuss your experience and let us know what you think! We hope you enjoy the changes and look forward to your feedback!
Update as of 02/20/2020 – Thank you to the Microsoft Edge Insider Community for continuing to test and provide feedback on Microsoft Edge. Your testing and feedback helped us identify a compatibility issue with a third party app that we’re actively working to address. We’ve modified the optimizations to mitigate the issue and expect you’ll see more modest performance improvements in the upcoming Beta Channel build. Please continue hammering on the Canary and Dev builds and sending us feedback!

Bringing the Microsoft Edge DevTools to more languages – Microsoft Edge Blog

We know inclusivity makes us work better and we love when we find ways to put that knowledge into practice. On the Edge team, we believe—and usage and research show—that developer experiences are more productive when they fit our language and location preferences. Today, we’re excited to move in that direction by announcing that the new Microsoft Edge now features DevTools localized in 10 languages (in addition to English):
Chinese (Simplified) – 中文(简体)(简体)
Chinese (Traditional) – 中文(繁體)(繁體)
French – français
German – deutsch
Italian – italiano
Portuguese – português
Korean – 한국어
Japanese – 日本語
Russian – русский
Spanish – español
This adds our new browser tools to a long list of other localized Microsoft developer experiences including VS Code, Azure Portal, and more.
This release is the result of collaboration over many months between our team and the DevTools, Lighthouse, and Chrome teams at Google. We’ve contributed all localizability features upstream (explainer), and plan to continue to do so so that other browsers can benefit from this work.
Try the localized developer tools
Make sure you have “Enable localized Developer Tools” turned on by heading to edge://flags, finding that flag, and setting it to “Enabled” (this is on by default in Canary; on by default soon in Dev, Beta, and Stable channels). Once on, your DevTools will match the language of the browser. On macOS, the developer tools inherit the language from the operating system. You can change the language in the Settings under the “Language and Region” section. Add another language, change it to your primary. Once you restart Microsoft Edge, the developer tools will be in that language.
If you just wanted to try the feature out and wish to revert to English, go to DevTools Settings (F1) > Preferences and click the checkbox to deselect “Match browser language.”

What’s next
For the initial release, we went with the top languages used by web developers within our ecosystem. Next, we’re evaluating popular right-to-left languages like Hebrew and Arabic and working on localizing our documentation. If you’d like those languages or other features in the localization and internationalization space, please let us know. We’re always happy to hear your thoughts.

Debug z-index stacking content with 3D View in the Microsoft Edge DevTools – Microsoft Edge Blog

We are thrilled to announce the next iteration of 3D View in the Microsoft Edge DevTools, with a new feature to help debug z-index stacking context. The general 3D View shows a representation of the DOM (Document Object Model) depth using color and stacking, and the z-Index view helps you isolate the different stacking contexts of your page.
3D view is enabled by default in the Canary branch – to enable it in other branches, open the DevTools “Experiments” settings (Ctrl-Shift-P -> “Experiments“) and turn on “Enable 3D View.” If you don’t see that item, navigate to edge://flags and make sure you have enabled “Developer Tools experiments.” Once 3D view is enabled, you can find it under the “More tools” menu (or via search: Ctrl-Shift-P -> “3D View“).

With our first 3D View experiment, we were able to get incredible feedback from Twitter and from the feedback button. This encouraged us to conduct further usability studies to improve the tool. Along the way, we received plenty of requests for CSS z-index debugging as a feature, and felt that the 3D View would be a great vehicle to try it out.
In the z-index tab you can further simplify the view by only showing elements with a stacking context or hiding elements with the same paint order as their parent. These two settings will make for a flatter and more readable experience. Check out our explainer for more details!

What’s next
Coming soon, we’ll have a better highlighting experience between the Elements panel and 3D View, UI improvements, and new camera controls. We’d love to hear what else you’d like to see from this experience! What other features would help you with your day to day debugging? Feel free to reach out to us on Twitter, or just click “Send feedback” in the Microsoft Edge “Help and Feedback” menu at any time.
