Accessibility improvements to the DevTools
The DevTools team has contributed 170 changes to Chromium to address high-impact color contrast, keyboard, and screen reader issues in the DevTools. Every developer building the web should be able to use the DevTools.
Chromium issue #963183
Using the DevTools in other languages
Many developers use other developer tools, like StackOverflow and Visual Studio Code, in their native language, not just in English. We’re excited to announce localization for the DevTools, which you are now able to use in one of 10 languages besides English:
Chinese (Simplified) - 中文（简体）
Chinese (Traditional) - 中文（繁體）
French – français
German - deutsch
Italian - italiano
Japanese - 日本語
Korean - 한국어
Portuguese - português
Russian – русский
Spanish - español
The DevTools automatically match the language you use for Microsoft Edge in
If you want Microsoft Edge to be in one language and your DevTools to remain in English, press
F1 in the DevTools to open Settings and disable Match browser language.
Console messages are not localized. Only the strings used in the DevTools UI are displayed in the language you use for Microsoft Edge.
Chromium issue #941561
webhint Microsoft Edge extension
The webhint Microsoft Edge extension allows you to easily scan your web page and get feedback on accessibility, browser compatibility, security, performance, and more within the DevTools. Read more at https://webhint.io.
Try the webhint browser extension in Microsoft Edge. Once you install the extension, open the DevTools and select the Hints tab. From here, run a customizable site scan. Head over to webhint.io to learn more.
To access the 3D View, press
P, type in 3D View and select Show 3D View.
We're working on the UI and adding more functionality to the 3D View, so please send us your feedback.
Chromium issue #987787
Visual Studio Code extensions
The DevTools team has also released some extensions for Visual Studio Code that let you use the power of the DevTools directly from your text editor! Check out the extensions below:
Elements for Microsoft Edge
Use the Elements tool from within Visual Studio Code by adding the Elements for Microsoft Edge (Chromium) Visual Studio Code extension.
For more information, check out Elements for Microsoft Edge Visual Studio Code extension.
Debugger for Microsoft Edge
For more information, check out how to debug Microsoft Edge from Visual Studio Code.
The webhint Visual Studio Code extension uses
webhint to improve your web page while you're writing it! This extension runs and reports diagnostics on your workspace files based on
Visual Studio integration
Tracking prevention Console messages
Tracking prevention is a unique feature in Microsoft Edge that protects you from being tracked by websites you haven't visited before. The default tracking prevention setting is Balanced mode, which blocks 3rd party trackers and known malicious trackers for an experience that balances privacy and web compatibility. To give you more insight into the compatibility of your web page when certain trackers are blocked, we've also added warning messages in the Console when a tracker is blocked.
Announcements from the Chromium project
The following sections announce additional features available in Microsoft Edge 81 that were contributed to the open source Chromium project.
Moto G4 support in Device Mode
After enabling the Device Toolbar, simulate the dimensions of a Moto G4 viewport from the Device list.
Click Show Device Frame to show the Moto G4 hardware around the viewport.
- Open the Command Menu and run the
Capture screenshotcommand to take a screenshot of the viewport that includes the Moto G4 hardware (after enabling Show Device Frame).
- Throttle the network and CPU to more accurately simulate a mobile user's web browsing conditions.
Chromium issue #924693
Blocked cookies in the Cookies pane
The Cookies pane in the Application panel now displays blocked cookies with a yellow background.
Chromium issue #1030258
Cookie priority in the Cookie pane
The Cookies tables in the Network and Application panels now include a Priority column.
Chromium-based browsers, like Microsoft Edge, are the only browsers that support cookie priority.
Chromium issue #1026879
Edit all cookie values
All cells in the Cookie tables are editable now, except cells in the Size column because that column represents the network size of the cookie, in bytes. See Fields for an explanation of each column.
Copy as Node.js fetch to include cookie data
Right-click a network request and select Copy > Copy as Node.js fetch to get a
fetch expression that includes cookie data.
Chromium issue #1029826
More accurate web app manifest icons
Previously, the Manifest pane in the Application panel sent its own requests in order to display web app manifest icons. DevTools now shows the exact same manifest icon that Microsoft Edge uses.
Chromium issue #985402
Hover over CSS content properties to see unescaped values
Hover over the value of a
content property to see the unescaped version of the value.
For example, in this demo when you inspect the
p::after pseudo-element you see an escaped string in the Styles pane:
When you hover over the
content value you see the unescaped value:
More detailed source map errors in the Console
The Console now provides more detail on why a source map failed to load or parse. Previously it just provided an error without explaining what went wrong.
Setting for disabling scrolling past the end of a file
Open Settings and then disable Preferences > Sources > Allow scrolling past end of file to disable the default UI behavior that allows you to scroll well past the end of a file in the Sources panel.
