Microsoft Edge Dev

As promised last week, Microsoft has just released the final major version 91 build to the Edge Dev Channel. It comes in at build 91.0.864.1. There still could be some small patches incoming, before now and when this build hits the Beta branch soon, but here’s a look at everything you need to know.

Since this is the end of a major Microsoft Edge release schedule, there’s not anything big to note in this build. There are some added options in menus here and there, but that’s just about it. Here are the added features to take note of.

  • Added options to print documents at their actual size or to fit them to the page.
  • Added an option to prompt before closing a window with multiple tabs open.
  • Added the ability to clear Media Foundation data on demand. Note that on-exit is coming later.
  • Enabled Math Helper by default on Mac and Windows now that the rollout has completed.
  • Added a management policy to enable Math Solver.
  • Enabled support for the Chromium management policy to control Explicitly
  • Allowed Network Ports.
  • Added support for ClickOnce on Windows 7.

As for what else you need to know about in this release, Microsoft has fixed the usual crashes that you might have been experiencing here and there. They also changed some behaviors, too. Fixed crashes cover dragging and dropping tabs, interacting with the Favorites popup, sorting Collections, closing tabs while popups like the Find On Page bar are open, and more. You can check below for everything you need to know.

  • Fixed an issue where the favicons for the Top Sites tiles on the New Tab Page are broken.
  • Fixed a crash on launch that makes it appear as though the browser isn’t opening.
  • Fixed an issue where certain websites crash a few seconds after loading.
  • Fixed an issue where Collections appear to have no items in them even though they do.
  • Fixed an issue Collections deletes and undeletes sometimes don’t work or don’t sync.
  • Fixed an issue where the Site Information popup incorrectly states that webpages currently being viewed in Immersive Reader are aren’t secure even though the original webpage was.
  • Fixed an issue where the management policy to Save Cookies On Exit isn’t working for certain websites when the Default Cookies Setting is set to delete cookies on exit (option 4).
  • Fixed an issue on Linux where online voices for Read Aloud sometimes aren’t working.
  • Fixed an issue where the basic authentication prompt appears for websites when the Windows Hello prompt is expected because a management policy is set.
    Improved the Immersive Reader keyboard shortcut to apply to more pages.
  • Fixed an issue where Immersive Reader eligibility for some pages unexpectedly disappears when interacting with the pages.
  • Fixed an issue tab drag and drop sometimes doesn’t work with vertical tabs if tabs are pinned.
  • Fixed an issue where websites that are installed as apps sometimes don’t handle links that should open in them (instead, the links open in regular tabs).
  • Fixed an issue where translating web pages can sometimes cause content on them to disappear.
  • Fixed an issue where dropdowns on webpages appear to be autofill data even when they aren’t.
  • Fixed an issue where the Device Mode button in the F12 Dev Tools sometimes doesn’t work.
  • Fixed an issue where right-clicking on Collections sometimes doesn’t bring up the correct menu.
  • Fixed an issue where popups from IE mode tabs sometimes open in regular tabs instead of IE ones.
    Obsoleted the management policy to enable Proactive Auth

Known issues in this final version 91 build have not changed. Microsoft has quite some work to do, it seems, on this end, as these known issues are the same as the past Dev Channel cycles. Certain extensions such as the Microsoft Editor extension don’t work on Linux, ad blocking extensions might cause playback errors on YouTube, and all tabs and extensions immediately crash with a STATUS_INVALID_IMAGE_HASH error. Other known issues include Users of the Kaspersky Internet Suite not being able to load Gmail, favorites being duplicated, and wobbling with scrolling.

That’s all we have for this week. Happy downloading, Edge Insiders, and remember to send your feedback to Microsoft if you come across any bugs.
