Microsoft Edge Dev Build 100.0.1185.7 Released

Microsoft has released a new Chromium-based Microsoft Edge build number 100.0.1185.7 for the Dev channel, which brought with it several new features, as well as various fixes and improvements. Microsoft will soon move on to testing version 101 on the Dev channel.

Main innovations:

  • Clarity Boost support for Xbox Cloud Gaming is enabled by default.
  • Added a hint for automatically logging in to sites (with the same account that is used to log in to the browser) that do not allow this, because the user was previously logged out.
  • Policies (documentation and administrative templates will be updated later):
    • Added a policy to control whether the Edge Asset Delivery Service is enabled. This service is used by the browser to load various configuration files and machine learning models that enable certain features.
    • Added support for the PDF Secure Mode control policy, which controls the digital signature verification of PDF files.
  • For developers:
    • Added API to WebView2 to update status bar text. This API was previously experimental. The SDK documentation has probably not been updated yet.
    • Added support for icons with no values ​​for PWA labels to indicate that the site wants to set up an alert but doesn’t want text on the icon.

Fixes to improve stability:

  • Fixed a crash when using the “Find on Page” feature.
  • Fixed a crash when opening certain PDF files.
  • Fixed crash when interacting with IE mode tabs.
  • Fixed crash when refreshing IE mode tabs.
  • We fixed an issue where sometimes the browser could not navigate to some websites. The download took forever.
  • Smartphones:
    • Fixed crash when browsing tabs.
    • Fixed a crash when using some features of the Purchases module.
    • Fixed a crash when using the Read Aloud feature.

Other fixes and changes:

  • Reduced the number of extensions blocking the Startup Boost feature.
  • We fixed an issue that caused the browser to reopen immediately after closing.
  • We fixed an issue where Family Safety sometimes didn’t work. Instead, a normal window was launched.
  • We fixed an issue where clicking on websites pinned to the taskbar would sometimes activate an existing tab for that site, rather than creating a new tab for that site.
  • We fixed an issue where websites sometimes pinned to the taskbar with the wrong icon when multiple pages of the same site were pinned.
  • We fixed an issue where some buttons could not be hidden from the toolbar.
  • We fixed an issue where tab groups in some menus had the wrong colors.
  • Politicians:
    • We fixed an issue resulting in some versions of Windows reporting that they don’t support enterprise governance when they don’t.
    • We fixed an issue where the policy to enable address bar editing in kiosk mode sometimes didn’t work.
    • Removed policy support from Chromium that controls which sites should display the padlock icon in the address bar.
  • Smartphones:
    • We fixed an issue that sometimes caused downloaded files to not open.
    • We fixed an issue resulting in sometimes failing to download files and then upload them to OneDrive.
    • Fixed an issue that sometimes failed to switch profiles after using the Guided Switch feature
    • We fixed an issue resulting in some websites failing to close cookie consent dialogs.

Known Bugs:

  • Users of some ad blocking extensions may experience playback errors on YouTube. As a workaround, it is recommended to disable the corresponding extension. More detailed information here.
  • Some users are still experiencing an error where all tabs and extensions stop working with a STATUS_INVALID_IMAGE_HASH error. The most common cause of this error is outdated security software or antivirus software from vendors such as Symantec, in which cases a software update will fix the error.
  • Users of Kaspersky Internet Suite who have the appropriate extension installed may sometimes find that some web pages, such as Gmail, do not load. This failure occurs due to the use of outdated core Kaspersky software, therefore it is solved by installing the current version.
  • Some users may experience web page ‘wobble’ when scrolling with touchscreen or trackpad gestures, where scrolling in one dimension also causes a subtle scrolling in the other dimension. The issue is reported to only occur on certain web pages and appears to be more severe on some devices. This is most likely because the team is working on creating edge-legacy-compliant scrolling. If you are annoyed by the scrolling issue, then you can temporarily disable the experimental flag: edge://flags/#edge-experimental-scrolling.

If you are already using Edge Dev on your computer, you will receive the update automatically as soon as possible. If you want to speed up the process, then open the browser, go to “Settings” in the section “About Microsoft Edge”, after which the browser update will begin.

You can download Microsoft Edge Dev based on Chromium from the official website Edge Insider.
