110.0 Firefox Release

February 14, 2023

Version 110.0, first offered to Release channel users on February 14, 2023


  • It's now possible to import bookmarks, history and passwords not only from Edge, Chrome or Safari but also from Opera, Opera GX, and Vivaldi for all the folks who want to move over to Firefox instead!

  • GPU sandboxing has been enabled on Windows.

    Note: A bug in the popular X-Mouse Button Control (XMBC) tool may cause mouse wheel scrolling to stop working. Affected users should update to the latest version of XMBC (2.20 or higher) which contains a fix for this issue.

  • On Windows, third-party modules can now be blocked from injecting themselves into Firefox, which can be helpful if they are causing crashes or other undesirable behavior.

  • Date, time, and datetime-local input fields can now be cleared with Cmd+Backspace and Cmd+Delete shortcut on macOS and Ctrl+Backspace and Ctrl+Delete on Windows and Linux.

  • GPU-accelerated Canvas2D is enabled by default on macOS and Linux.

  • WebGL performance improvement on Windows, MacOS and Linux.

  • Enables overlay of hardware-decoded video with non-Intel GPUs on Windows 10/11, improving video playback performance and video scaling quality.



  • Colorways are no longer available in Firefox, at least not in the same way. You can still access your saved and active Colorways by selecting Add-ons and themes from the Firefox menu. Additionally, you can now install Colorways from all of the previous collections by visiting Colorways by Firefox on the Mozilla Add-ons website.


Web Platform

  • Firefox now supports CSS named pages, allowing web pages to perform per-page layout and add page-breaks in a declarative manner when printing.

  • Firefox now supports CSS size container queries, see the MDN page for documentation on this feature.
