The Firefox browser has been updated to version 94.0b3. This update to the Dev channel was released on October 9, 2021.

Firefox Dev 94.0b3

Firefox Dev 94.0b3 comes with a total of 13 bug fixes, which can be viewed from the changelog below. Of the 13 bugs, 11 of them were defects while two are new tasks that have been introduced.

The two new tasks that have been enabled are related to WebAssembly sandboxing. The two separate tasks appear to enable the same thing but just on different platforms as the 32-bit version of Windows seemingly demands its own file. As for the bugs that were addressed, there doesn’t appear to be anything noteworthy outside of a fix for YouTube videos that were known to be stuttering (I did see several people complaining about this).

The official changelog provided by Firefox:

  • Warm and cold pageloads are being combined into a single value
  • Enable wasm sandboxing on 32-bits Windows and Linux
  • Enable wasm sandboxing on all remaining platforms on automation
  • Intermittent org.mozilla.geckoview.test.PrivateModeTest#privateDataNotShared | application crashed [@ mozilla::dom::BrowsingContext::Detach(bool)]
  • YouTube videos intermittently stutter
  • [Wayland/KDE] Popup menus become small again in new version
  • Perma Raptor failures: AttributeError: ‘WebExtension<something>’ object has no attribute ‘page_count’
  • bookmarks folder list in Add bookmark/Edit bookmark panel is white on white/not readable with dark theme
  • Consider Never Automatically Unloading WebRTC Tabs
  • Poor contrast on Manage Themes link in some themes
  • There are extra characters added in the name of the selected theme if a colorway is clicked twice
  • “Show you how” session-restore infobar button should perhaps say “Show **me** how”
  • [Monochromatic Themes] The user and password field in the Save login panel has a black backgroud while using Bold and Balanced themes

Some users are claiming that the beta version of Firefox 94 are running smoother on linux than they were before. This can be seen in the rendering seepd in compairson to Firefox 93 on linux.

Further information regarding these bugs is available here: Bug ID: 1722171, 1734155, 1733002, 1734127, 1732430, 1734655, 1727266, 1727678, 1734246, 1734164, 1732911, 1732682, 1733744.

The Firefox browser will automatically update itself in the background when it’s closed. If the browser is open and you want to update it, you can navigate to the Settings > Help > About Firefox, and then the browser will automatically check for any new updates.
