Dev channel update to 90.0.789.1 is live

Hello Insiders!  Today we’re releasing build 90.0.789.1 to the Dev channel.  Before we get into the changes, we wanted to make sure you knew about the latest status of our password management feature within the Microsoft Authenticator app.  We’ve got all the details here:  https://blogs.windows.com/windowsexperience/2021/02/05/simplify-and-secure-your-life-with-microsofts-autofill-solution-for-passwords/.  Additionally, for enterprises and IT managers, we know you’ve been eagerly awaiting our kiosk mode work, and we’ve got an update on that here:  https://blogs.windows.com/msedgedev/2021/02/05/what-you-need-to-know-about-kiosk-mode-when-support-for-microsoft-edge-legacy-ends/. 

Now, for everything in the product: 

Added features: 

• Added options for a simplified right-click menu for PDFs.  Note that actual changes to the right-click menu are still being rolled out, so these settings may not be functional yet. 
• Added management policies for Quick View Office Files Enabled, which controls whether or not Office files can be opened directly in Edge instead of being downloaded, and for Application Guard Favorites Sync Enabled to control whether or not Application Guard windows should have access to the same set of Favorites as non-Application Guard windows.  Note that updates to administrative templates or documentation may not have occurred yet.   

Improved reliability: 

• Fixed a hang on shutdown that may prevent Edge from opening correctly. 
• Fixed an issue on Mac running on ARM where all tabs immediately crash as soon as they’re opened.

• Fixed an issue where the ability to pin a PWA or website installed as an app to the start menu or desktop by right-clicking its entry in edge://apps is missing. 
• Fixed an issue where uninstalling a PWA or website installed as an app from the Start Menu sometimes doesn’t remove its entry from edge://apps. 
• Fixed an issue where pending download items sometimes aren’t initially visible in the Downloads popup menu. 
• Improved the appearance of the Favorites and History menus on small screens. 
• Fixed an issue when searching for History using the History menu and no results are returned.

• Fixed an issue where the management policy for New Tab Page Hide Default Top Sites doesn’t work. 
• Fixed an issue where the management policy for Kiosk Address Bar Editing Enabled does the opposite of what it says it does. 

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 https://techcommunity.microsoft.com/t5/articles/known-issue-adblock-causing-errors-on-youtube/m-p/14... 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 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.  This issue should be reduced now that automatic deduplication has been introduced into Insider channels.  However, 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 while we wait for the automatic deduplication to make it to Stable, 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 all the valuable feedback you provide!
