Version 103.0, first offered to Release channel users on July 26, 2022

New

  • Improved responsiveness on macOS during periods of high CPU load by switching to a modern lock API.

  • Do you always forget something? Required fields are now highlighted in PDF forms.

  • Improved performance on high-refresh rate monitors (120Hz+).

  • Enjoying Picture-in-Picture subtitles feature? It just got better: you can now change subtitles font size directly from the PiP window. Additionally, PiP subtitles are now available at Funimation, Dailymotion, Tubi, Hotstar, and SonyLIV.

  • Buttons in the Tabs toolbar can now be reached with Tab, Shift+Tab, and Arrow keys. View this article for additional details.

  • Windows’ “Make text bigger” accessibility setting now affects all the UI and content pages, rather than only applying to system font sizes.

  • Rejoice! You can now conveniently access Firefox, which will now be pinned to the Windows taskbar during installation on Windows 10 and 11. (This will also allow for Firefox to be launched quicker after installing.)

Fixed

  • Non-breaking spaces are now preserved—preventing automatic line breaks—when copying text from a form control.

  • Fixed WebGL performance issues on NVIDIA binary drivers via DMA-Buf on Linux.

  • Fixed an issue in which Firefox startup could be significantly slowed down by the processing of Web content local storage. This had the greatest impact on users with platter hard drives and significant local storage.

  • Various security fixes.

Changed

  • Removed a configuration option to allow SHA-1 signatures in certificates: SHA-1 signatures in certificates—long since determined to no longer be secure enough—are now not supported.

talk about a buried lede:

Congrats to the Firefox team for finally enabling this behavior by default. It’s only 28 years overdue!

Yes, it has taken a long time because many web pages were breaking when it was activated (especially on Facebook, Google and other pages). Glad to see it’s finally on the stable branch!
