Dev channel update to 84.0.522.5 is live


Hello Insiders!  Today we’re releasing build 84.0.522.5 to the Dev channel.  We expect this to be the final build for major version 84, give or take a few small patches past .5.  In community news, we’re excited to share an overview of our surf game to celebrate its arrival in Stable after Stable’s recent update to major version 83:  The surf game was originally the final part of the hidden journey to unveil our new logo last November, and now is a fun game you can play if you ever find yourself offline (or anytime!)  We also posted about the improvements we’ve been making to spellcheck:


In product news, we’re excited to announce that Read Aloud is now available in PDFs!  We put together an overview of it here:  We also have a small preview of what to expect from Sidebar Search here:  In other news: 


Added features: 


  • Added support for Read Aloud in PDFs. 
  • Added support for full page translation in Immersive Reader. 
  • Added the ability for text saved to a Collection to take you back to the location on the webpage it came from. 
  • Added back support for the Chromium “Force Dark Mode for Web Contents” flag. 
  • Enabled Shy UI on Mac. 
  • Added support for the F6 key to change focus on Mac. 


Improved reliability: 


  • Fixed an issue where certain types of videos like HEVC don’t play properly. 
  • Fixed an issue where webpages with videos sometimes hang. 


Changed behavior: 


  • Fixed an issue where attempting to save an edited PDF brings up the “Save As” dialog every time it’s saved instead of silently saving. 
  • Fixed an issue where the Find on Page popup sometimes gets stuck and can’t be interacted with. 
  • Fixed an issue where history entries in the Jumplist sometimes aren’t cleared after closing the browser when history is set to be cleared on close. 
  • Fixed an issue where favorites on the Favorites Bar sometimes forget that they’re supposed to be icon only. 
  • Fixed an issue where extensions that allow keyboard shortcuts to be set aren’t able to have those shortcuts be changed on edge://extensions/shortcuts. 
  • Fixed an issue where autofill popups sometimes appear when they shouldn’t with incorrect suggestions. 
  • Fixed an issue where browser profiles associated with a work or school account are sometimes unintentionally signed out or removed. 
  • Fixed an issue on Mac where languages on the Language Settings page sometimes can’t be selected to “Offer to translate pages in this language”. 
  • Fixed an issue where starting Read Aloud on certain pages leaves Edge in a state where Read Aloud can’t be stopped even though there’s nothing to read. 


Known issues: 


  • Tabs sometimes appear squished or too small, even when there are only a few of them.  This is most often caused by clicking a link in a different program that opens a new tab in Edge, and can usually be fixed by changing the size of the tab band, for example by resizing the window. 
  • 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 seeing favorites get duplicated after we made some previous fixes in that area. The most common way this is triggered is by installing the Stable channel of Edge and then signing into it with an account that has already signed into Edge before.  Fixing this should be easier now that the deduplicator tool is available.  However, we’ve also seen duplication happen when running the deduplicator on multiple machines before either machine has a chance to fully sync its changes, so while we wait for some of the fixes we’ve made to come to Stable, make sure to leave plenty of time in between runs of the deduplicator.  We hope that this will be improved now that version 81 is released to Stable. 
  • After an initial fix for it recently, some users are still experiencing Edge windows becoming all black.  Opening the Browser Task Manager (keyboard shortcut is shift + esc) and killing the GPU process usually fixes it.  Note that this only appears to affect users with certain hardware and is most easily triggered by resizing an Edge window. 
  • 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. 
  • 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. 


Thanks to you, look for this build to be heading to Beta soon!

No, there is no update on my browser, still waiting. @josh_bodner

@josh_bodner That feature to take you back to the text added to a collection is awesome! It's such a cool feature I'm surprised it wasn't called out as a NEW tile on the page that opens when after the browser updates telling you what's new.


Also... any idea when that crazy squished tab known issue will be fixed? It's been around for a couple builds now.


Thank you!

@josh_bodner on the subject of Collections,, I would really appreciate if there was a way to expand the sidebar to a full page to easily manage Collection contents. As it is right now, it feels pretty cramped for more than a few handful of items. Once the amount of Collections and items grows, it becomes tedious to manage. It's good for a quick glance though.

Tried out READ-ALOUD with a PDF - a bit hard with hyperlinks embedded in any file, to select stuff - suddenly, you're at page 11. Also, in any application that has defined keystrokes, like MS Word, Ctrl+Shift+U is problematic - it just underlines the text. To highlight, right-click is preferable. Strange, voices - in a browser, the voice is female; in a PDF, it was male. Assuming that it will be possible to select a voice in Windows 10 appropriately (US accent is a bit grating for Aussies).

@josh_bodner I was just wondering when are the Vertical Tabs featured that was annouced at Build coming to the Insider releases specifically the Dev channel.

@josh_bodner Loving the new Edge and all you guys have been doing over the last year. The squished tab thing has been around for a few releases now and is very annoying - be great to have that one sorted as a priority.



Sent feedback already several times, but I will try again here.


The following behavior still not changed: I have configured to open specific pages on startup. But also, an additional tab (start page) always opens along the defined pages. This is not expected behavior I guess...


Maybe you can look into this...

Black windows issue is with AMD drivers.
edge://surf still consumes a lot of GPU and CPU resources

@josh_bodner I can confirm HEVC is now playing as expected, compared to the last dev build. Thanks for looking in to it!

I can confirm that. The problem is, that the NewTab page is the one that is focused on open.

Since this update Edge crashes completely whenever I try to make a web app full screen on macOS

I can make the main browser window full screen, but not apps :frowning_face:

Hello Insiders!  Today we’re releasing build 84.0.522.5 to the Dev channel. 

  • Fixed an issue where browser profiles associated with a work or school account are sometimes unintentionally signed out or removed. 

@josh_bodner, profile switching is now back to working as it should. Thanks Edge team for the quick fix. :thumbs_up:

@Joshua_HV squished tabs should be fixed in today's Canary, which hopefully means the fix will also make it to next week's Dev.  

@WesternWombat_99 you should be able to change the voice with the voice options button on the Read Aloud bar:  



@sprite-1 I'll ask our Collections team if this is on their backlog, but you should also file feedback so we get accurate counts in our feedback database.  

@cloud_entropy does this only happen with your current profile?  In other words, if you add a new profile to the browser and try to set some startup pages, does the extra tab also appear in that new profile?  

@KibosJ Thanks for finding this, I'll make sure our web apps team knows about it!

I just filed the feedback
