Edge Dev build 81.0.403.1 is out with 3D viewer

It's once again time for a new build of Edge Dev, the version of Microsoft's Chromium-based Edge browser that's updated weekly. The version for this week's build is 81.0.403.1. As usual, there's not a whole lot that's new, with Microsoft only adding a few minor new features.

Here are the new features:

  • Enabled the 3D viewer tool in the F12 Developer Tools.
  • Enabled localization of the F12 Dev tools so they will match the language the rest of the browser is using.
  • Enabled the link on the … menu to the Extensions management page in Application Guard windows now that extensions have been enabled.

There are also some fixes for improved reliability:

  • Fixed an issue where navigating to certain websites causes a browser crash.
  • Fixed an issue where websites that use Windows’ credential prompt in order to log in sometimes cause a browser crash.
  • Fixed an issue where using Collections sometimes causes a browser crash when closing a window.
  • Fixed an issue where certain DRM-protected video doesn’t play on Windows Insider builds.
  • Fixed an issue where certain DRM-protected video doesn’t play on certain devices.

There are also some fixes for improved behavior:

  • Temporarily hid the Global Media Controls button that was inherited from Chromium.
  • Improved the white flashes that sometimes occur in Dark Theme when loading internal webpages like Favorites, History, etc.
  • Fixed an issue where Spellcheck is sometimes not enabled by default.
  • Fixed an issue where editing favorites on the Favorites management page sometimes causes folders to unexpectedly close or open.
  • Improved Browser Task Manager’s persistence of column widths.
  • Fixed an issue where there were two context menu entries to move a tab to a new window.
  • Fixed an issue where attempting to translate a page into the same language it’s already in causes the Translate popup not to show the current language correctly.
  • Fixed an issue where the Done or Next button sometimes doesn’t appear during the First Run Experience.
  • Fixed an issue where parts of Collections are inappropriately hidden when the browser’s zoom level is set to greater than 100%.
  • Fixed an issue where pressing Shift+Tab when editing text in a Collection unexpectedly exits text editing mode.
  • Fixed an issue where pasting text into a Collection sometimes shows black on dark text when using Dark Theme.
  • Fixed text formatting issues when pasting text into a Collection.
  • Fixed an issue where the option to Read Aloud is shown in places where it can’t be used.
  • Fixed an issue where the list of voices available in Read Aloud sometimes isn’t correct.
  • Fixed an issue where Read Aloud sometimes doesn’t read long phrases properly when using certain voices.
  • Fixed an issue on Mac where websites installed as apps still have a too-tall title bar.

Finally, there are some known issues to be aware of:

  • The dialog to install a website as an app sometimes doesn’t appear.
  • Users of certain security software packages will see all tabs fail to load with the error STATUS_ACCESS_VIOLATION. The only way to prevent this behavior is to uninstall that software.
  • After an initial fix for it recently, some users are still experiencing Edge windows becoming all black. UI popups like menus are not affected and opening the Browser Task Manager (keyboard shortcut is shift + esc) and killing the GPU process fixes it. Note that some of these fixes don’t yet exist in the Stable channel, and the issue only appears to affect users with certain hardware.
  • Some users are still not seeing Collections being enabled by default on Canary and Dev. For users who want to try Collections, enabling the flag at edge://flags/#edge-collections should still work to turn on the feature.
  • There are some issues where users with multiple audio output devices sometimes don’t get any sound from Edge. In one case, Edge becomes muted in the Windows Volume Mixer and unmuting it fixes it. In another, restarting the browser fixes it.
  • At certain zoom levels, there is a noticeable line between the browser UI and the web contents.

Microsoft released its Chromium-powered Edge browser to the world just a couple of weeks ago, which means that you don't have to be running the Canary, Dev, or Beta channel if you don't want to. It's easy enough to just run the browser that's part of Windows 10 at this point. However, there are of course some features that are exclusive to non-stable channels. Collections is only in Canary and Dev, and ARM64 support is only in Canary, Dev, and Beta.
