Microsoft today released a new Dev build of Microsoft Edge. By issuing version 84.0.522.5 to the Dev channel, Microsoft has noted that it can be the last Edge release built on top of Chromium 84. The next release should use Chromium 85.Edge Dev BannerEdge Dev 84.0.522.5 comes with the following highlights.

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.

Microsoft Edge is now a Chromium-based browser with a number of exclusive features like Read Aloud and services tied to Microsoft instead of Google. The browser has already received a few updates, with support for ARM64 devices in Edge Stable 80. Also, Microsoft Edge is still supporting a number of aging Windows versions, including Windows 7, which has recently reached its end of support. Check out Windows Versions Supported by Microsoft Edge Chromium and Edge Chromium latest roadmap. Finally, interested users can download MSI installers for deployment and customization.

For pre-release versions, Microsoft is currently using three channels to deliver updates to Edge Insiders. The Canary channel receives updates daily (except Saturday and Sunday), the Dev channel is getting updates weekly, and the Beta channel is updated every 6 weeks. Microsoft is going to support Edge Chromium on Windows 7, 8.1 and 10, alongside macOS, Linux (coming in the future) and mobile apps on iOS and Android. Windows 7 users will receive updates until July 15, 2021.

  1. Really hope they add back support to block autoplay as I don’t see a option to show option to block autoplay.
