Dev channel update to 100.0.1169.1 is live


Hello Insiders!  Today we’re releasing build 100.0.1169.1 to the Dev channel.  Our big news in today’s build is that we’ve finished rolling out two long-requested features:  the ability to view thumbnails of the pages of a PDF as a list and use them to navigate through the document in the same way as the Table of Contents, and the ability to set your own custom password for use as the Primary Password that protects all passwords before they’re autofilled into a webpage. 


Additionally, for web developers, we’ve got a good writeup of some recent work we’ve done to fix bugs in the F12 Dev Tools that were impacting your ability to find memory allocation bugs with your websites.  Read all about it here:  As for everything else that’s new and noteworthy in the browser this week: 


Added features: 


  • Added support for a textprediction attribute on forms in webpages that allows web developers to enable or disable text prediction similar to the way they can control spellcheck and autocomplete. 
  • Enabled support for custom text cursors on Windows. 
  • Added a Setting on Mac to allow the browser to be automatically updated for all device users. 
  • Added the ability on Android to have Read Aloud work when the tab or app is in the background. 
  • Enabled a management policy from Chromium to Force the Major Version number To the Minor Position In the User Agent string, which is a temporary policy to freeze the major version number at 99 and place the actual version number in the minor position, for example turning version into 
  • Developer (Note that these APIs were previously in the “Experimental” status): 
    • Added an API to WebView2 to hide buttons from the PDF toolbar. 
    • Added an API to WebView2 to Call Dev Tools Protocol Method For Session, which runs an asynchronous method on a specific WebView session. 
    • Added an API to WebView2 to control the Exclusive User Data Folder Access property, which prevents other WebViews and browser processes from accessing the user data folder. 
    • Added an API to WebView2 to Allow External Drop, which controls if objects from outside a WebView application are allowed to be dragged and dropped into it. 


Improved reliability: 


  • Fixed a crash on the new tab page. 
  • Fixed a crash when certain popups appear. 
  • Fixed a crash when interacting with the Shopping button. 
  • Fixed a crash on Mac. 
  • Fixed a crash on Mac when interacting with the address bar. 
  • Fixed an issue where certain websites crash. 
  • Mobile: 
    • Fixed a crash on launch on Android. 
    • Fixed a crash when using Read Aloud. 
    • Fixed a crash when checking for leaked passwords. 
    • Fixed a crash when signing into the browser.
    • Fixed a hang when signing into the browser.   


Changed behavior: 


  • Fixed an issue where certain sites like Spotify that play protected media don’t work. 
  • Fixed an issue where passwords saved in Settings sometimes can’t be removed. 
  • Fixed an issue where Spellcheck isn’t available for certain languages that it should be. 
  • Fixed an issue where printing sometimes fails. 
  • Fixed an issue where a prompt to save info like addresses into Autofill unexpectedly appears after filling unrelated data into forms. 
  • Fixed an issue where payment cards don’t sync when they should. 
  • Fixed an issue where certain buttons appear that shouldn’t when hovering over tabs. 
  • Fixed an issue where certain popups don’t have an X button to close them. 
  • Fixed an issue where Web Select sometimes doesn’t copy certain selected items properly. 
  • Fixed an issue where shortcuts on the Taskbar are sometimes duplicated. 
  • Fixed an issue where the navigation buttons in the Edge Bar sometimes don’t work. 
  • Fixed an issue in the Edge Bar where tabs sometimes can’t be reordered. 
  • Improved support for scrolling PDFs using a touchscreen. 
  • Mobile: 
    • Fixed an issue where credit card autofill sometimes doesn’t work.
    • Fixed an issue where Microsoft Rewards info is missing. 
    • Fixed an issue where Read Aloud sometimes doesn’t work. 
  • Enterprise (removed management policies): 
    • Removed the policy to control if Cloud Profile Reporting functionality is Enabled. 
    • Removed the policy to control if Cloud Extension Request functionality is Enabled. 
  • Developer: 
    • Fixed an issue in WebView2 apps where the Document Title property sometimes isn’t updated on navigation (Issue 2055). 
    • Fixed an issue where WebView2 apps sometimes hang when first opening or restoring from minimization (Issue 2079). 


Known issues: 


  • 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 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. 


Next week is the last scheduled week for version 100 in the Dev channel, so after that it’s on its way to Beta!

did this get pulled back ? i'm not being offered it...
Did the "force dark mode" flag get removed?
I also cannot find the dark mode flag.
Is a "SECURE NOTE" feature in the pipeline? It will make the Edge password manager a complete package for the average user. Have already sent in the Feedback.


please restore flag for force dark web content

Thank you for sharing



edge://flags/#temporary-unexpire-flags-m99 to bring it back. 
It was re-instated in Canary.

"Fixed an issue in the Edge Bar where tabs sometimes can’t be reordered. "

I think this fixed the troubles I had when reordering tab, I couldn't drop the tab back onto the window it started from. For example, if I wasn't careful while dragging the tab and moved cursor too much vertically (tabs on top, not on the side) so the tab jumped to a new window it wouldn't go back into the original window if I tried to drag it back over the tabs in the original window. I would have to drop the tab which made a new window the select "move to window" from the tab context menu.
