Microsoft Edge Dev

Timed perfectly for the mid-week schedule, Microsoft just pushed out a new Edge Dev channel release. This week’s release comes in at build 94.0.975.1 and introduces some improvements for Sleeping Tabs. As always, we have you covered with a look at everything you need to know.

We start first with the added features. With Sleeping Tabs, Microsoft added an option to put tabs to sleep after less than a minute of inactivity. Microsoft also added the ability to see how much resource savings Sleeping Tabs provide on the tab preview hover popup. You can see below for the other new features.

  • Added support for using PNG images as the custom icons of PWAs.
  • Enabled by default the ability to print to PDF in landscape layout.
  • Enabled by default the improved installation dialog for PWAs/websites as apps.
  • Added management policies:
  • To control if the Password Generator is Enabled
  • To control the Primary Password Setting on Mac
  • To control if Application Guard Passive Mode is Enabled, which ignores the trusted and untrusted site lists
  • To set the list to Add Edge Token To User Agent String For URLs, which is the list of sites that will see the “Edg” token appended to the UA String
  • Added an option to the management policy to control Extension Settings that determines if the extension icon is pinned to the toolbar.
  • Re-enabled Web Capture on Linux.

Like always, you’ll also find that this release has some reliability fixes and changed behaviors. These cover all kinds of crashes and bugs. Some of these are unique to Macs, however. We included all of these for you below. The list is quite short this week.

  • Fixed an issue where navigating to certain websites sometimes crashes the browser.
  • Fixed an issue where clicking a Restart button in Settings crashes the browser.
  • Fixed a crash during shutdown.
  • Fixed a hang on launch.
  • Fixed a crash on Android 12.
  • Fixed an issue where windows become unresponsive after unplugging a monitor.
  • Fixed an issue on Mac where the Appearance Settings page is blank.
  • Fixed an issue on M1 Macs where the Password Settings page is blank.
  • Fixed an issue where searching in Settings causes it to go blank.
  • Fixed an issue where saving a PDF sometimes fails.
  • Fixed an issue on mobile where profiles are removed after installing an update.
  • Fixed an issue where extensions don’t work in PWAs or websites installed as apps.
  • Fixed an issue where PWAs or websites installed as apps sometimes close on their own.
  • Fixed an issue where searches initiated from context menus sometimes open blank search pages instead of searching for the expected term.
  • Fixed an issue where sidebar searches sometimes don’t search for the correct text.
  • Fixed an issue where using touch to scroll the vertical tabs pane also changes which tab is active.
  • Fixed an issue where the Efficiency Mode toolbar icon sometimes can’t be hidden.
  • Fixed an issue where non-shopping websites are sometimes added to Collections as if they were shopping websites.
  • Fixed an issue where Collections are unexpectedly disabled.
  • Fixed an issue where the active tab sometimes changes unexpectedly when dragging tab groups.
  • Fixed an issue on Android where signing into Google fails.
  • Fixed an issue in WebView2 apps where controls like dropdowns sometimes don’t work because they appear behind the window instead of on top of it.
  • Fixed an issue where the entire browser sometimes flashes black when watching videos while browsing another page.
  • Replaced the management policy to control if the setting to Open Microsoft Links In Edge is Enabled with the policy to control if Enhanced Link Opening In Edge is Enabled.
  • Obsoleted the management policy to control if User Agent Client Hints are Enabled

We end with the known issues. These are the same as always. As a reminder, ad blocking extensions will mess with YouTube, tabs and extensions might crash with an error, Kaspersky internet suite might mess with Google webpages, favorites might get duplicated, and you might see wobbling when scrolling.

Happy downloading, Edge Insiders! And remember to submit your feedback on this release so you can help make Edge great for everyone.
