Updates 12/19/23 - Firefox

New

• Firefox now prompts Windows users to install the Microsoft AV1 Video Extension to enable hardware decoding support for the AV1 video codec from about:support if not already installed.

• Firefox now supports Voice Control commands on macOS systems.

• On Linux, Firefox now defaults to the Wayland compositor when available instead of XWayland. This brings support for touchpad & touchscreen gestures, swipe-to-nav, per-monitor DPI settings, better graphics performance, and more.

  Note that due to Wayland protocol limitations, Picture-in-Picture windows require an extra user interaction (generally right-click on the window) or a shell / desktop-environment tweak. See bug 1621261 for related discussion and tracking, this post for a KDE configuration, and this extension for GNOME.

• Firefox can now force links to always be underlined. This option can be enabled in the Browsing section of the Firefox Settings menu.

  

• The PDF viewer now includes a floating button to simplify deleting drawings, text, and images added in PDFs.

  

Fixed

• Various security fixes. (  https://www.mozilla.org/en-US/security/advisories/mfsa2023-56/ )
