Dev channel update to 91.0.845.2 is live


Hello Insiders!  Today we’re releasing build 91.0.845.2 to the Dev channel.  In community news this week, it’s a little quiet, but we’ve got lots of exciting features and fixes to talk about: 


Added features: 


  • Added the ability to select and delete multiple passwords at the same time from edge://settings/passwords. 
  • Added the ability to quickly toggle between two tabs on Mac via a keyboard shortcut.  Note that this is already available on Windows via Edge’s tab integration into the Alt+Tab switcher. 
  • Added a Certificate Management Settings page on Linux. 
  • Added a message to explain that Vertical Tabs can’t be collapsed when IE mode tabs are open. 


Improved reliability: 


  • Fixed a crash on Mac. 
  • Fixed some crashes when closing the browser. 
  • Fixed a crash when navigating to certain websites. 
  • Fixed a crash when opening menus from within the Downloads popup menu. 
  • Fixed an issue where signing into the browser with a personal Microsoft account (after there’s already one signed in) in order to verify it causes a crash on Linux. 


Changed behavior: 


  • Fixed an issue where sync sometimes fails with error code NETWORK_CONNECTION_UNAVAILABLE (ERR_SSL_CLIENT_AUTH_CERT_NEEDED). 
  • Fixed an issue where logging into certain websites sometimes fails. 
  • Fixed an issue where certain videos don’t play. 
  • Fixed some issues where Application Guard windows sometimes fail to open. 
  • Fixed an issue where extensions installed via management policies sometimes fail to install. 
  • Fixed an issue where multiple Edge shortcuts are sometimes present on the Windows Start menu. 
  • Fixed an issue where certain popups like the website permission prompt or the downloads menu appear cut off or with unexpected scroll bars to see all content. 
  • Fixed an issue where Web Capture area selection doesn’t appear to work on certain websites. 
  • Fixed an issue where disabling standalone IE and then navigating to a site that’s set to open in standalone IE sometimes results in an infinite loop of popups stating that “This action is restricted.” 
  • Fixed an issue where the button to enter Kids Mode is sometimes missing from the profile flyout. 
  • Temporarily disabled Web Capture on Linux. 


Known issues: 


  • Certain extensions such as the Microsoft Editor extension don’t work on Linux.  As soon as they’re installed, they crash and are disabled.  We’re currently investigating. 
  • Users of certain ad blocking extensions may experience playback errors on Youtube.  As a workaround, temporarily disabling the extension should allow playback to proceed.  See this help article for more details. 
  • Some users are still running into an issue where all tabs and extensions immediately crash with a STATUS_INVALID_IMAGE_HASH error.  The most common cause of this error is outdated security or antivirus software from vendors like Symantec, and in those cases, updating that software will fix it. 
  • Users of the Kaspersky Internet Suite who have the associated extension installed may sometimes see webpages like Gmail fail to load.  This failure is due to the main Kaspersky software being out of date, and is thus fixed by making sure the latest version is installed. 
  • Some users are still seeing favorites get duplicated.  This issue should be reduced now that automatic deduplication has been introduced into Insider channels, but we’re still rolling that out in Stable.  We’ve also seen duplication happen when running the manual deduplicator on multiple machines before either machine has a chance to fully sync its changes, so make sure to leave plenty of time in between runs of the deduplicator. 
  • Some users are seeing “wobbling” behavior when scrolling using trackpad gestures or touchscreens, where scrolling in one dimension also causes the page to subtly scroll back and forth in the other.  Note that this only affects certain websites and seems to be worse on certain devices.  This is most likely related to our ongoing work to bring scrolling back to parity with Edge Legacy’s behavior, so if this behavior is undesirable, you can temporarily turn it off by disabling the edge://flags/#edge-experimental-scrolling flag. 


As always, we couldn’t do this without you!

Nothing exciting at all, just a complete lack of addressing the issue you created when you removed the toolbar extension area in the More menu when you added the Extensions button. That UI remains unusable to me with the number of extensions I have nstalled iand frequently need to interact with. 1 Change the Extensions button so disabling it makes NO CHANGE to what extensions are visible in the toolbar, but the Extensions button itself is hidden. 2 Restore a usable UI for e.g. 15-30 toolbar extension buttons more than can be shown in the toolbar like the previous toolbar overflow area at the top of the More menu; or the same but separate from the More menu, dropping down from a toolbar overflow icon.  Until and unless you do this, I simply cannot use or recommend Edge. I just can't believe how much you wrecked a good UI in one change.

Hello Edge team,
Why can't we hide extension icons when the extension button is turned off? Hide from toolbar is grayed out.


Please fix the bug with the Downloads dissappering from the Downloads button.



Please fix a bug with tab hover cards wherein sliding from one tab to another causes the card to use the icon of the previous tab.

Where's the Math Solver? I can not find it in my edge 91.0.845.2 of linux-deepin OS.
You can activate on the edge flags
Go to edge://flags
Search for Math Solver in Microsoft Edge, activate and then restart the edge
After restarting, go to settings and in appearance select the Show Math Solver button

After that click on the math solver icon, it may take a while before it starts to work

Web capture disabled on Linux? It works fine here! I think I'll skip this update...

OK. I'll try it.
I am waiting for the new Windows 10 design to be released anyone here has got info on that?


Today I reinstalled Windows and downloaded Edge dev and now my Extensions menu button is missing. It's missing from adressbar and from Settings->Appearance 

Also when I right-click an extension button and select "Move to the menu" it disappear from the adressbar (probably it's being moved to the missing Extension menu)

in alt+tab edge doesn't show the thumbnail for the unopened tab.



I need the new big sur design icon for edge on mac.

Great news and thank you for sharing, I really love the new improvement for the password manager.
