121.0 Release Note
https://www.mozilla.org/en-US/firefox/121.0/releasenotes/
New︰
Firefox now prompts Windows users to install the Microsoft AV1 Video
https://apps.microsoft.com/detail/9MVZQVXJBQ9V
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.
https://apple.co/41BGQ83
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.

Enterprise︰

Developer︰
The Firefox Debugger now includes a new feature: an option to disable the
debugger; keyword on the current page. This feature is accessible via a new
checkbox in the Breakpoints side panel labeled Pause on debugger statement,
located next to the existing Pause on exceptions checkbox. By default, this
option is enabled, meaning that the debugger statements are active unless
manually disabled.

As part of our work on improving the accessibility of Firefox Developer
Tools, we've unified the focus indicator across the toolbox. The focus
indicator is now larger with improved contrast, featuring a white box-shadow
for enhanced visibility on blue backgrounds. Adjustments have also been made
to ensure clear visibility across shared components and frequently used
panels, preventing overlap with element borders or backgrounds.
Web Platform︰
The :has() selector is now supported. This allows authors to match an
https://developer.mozilla.org/docs/Web/CSS/:has
element that has, or "anchors", at least one element matching its relative
selector.
The hanging and each-line keywords are now supported for the text-indent
https://developer.mozilla.org/docs/Web/CSS/text-indent
CSS property, offering more convenient paragraph layout options for styles
such as bibliographies, poetry, etc.
The balance keyword is now supported for the text-wrap CSS property,
https://developer.mozilla.org/docs/Web/CSS/text-wrap
which can improve the appearance of short multi-line text blocks such as long
headings or captions by harmonizing the line lengths.
Lazy loading iframes are now supported (<iframe loading=lazy>). Lazy
https://developer.mozilla.org/docs/Web/Performance/Lazy_loading
loading iframes are only loaded when visible, so non-critical iframes can
load later when needed to speed up initial page loads, reduce initial network
usage, etc.
Support has been added for tail call elimination in WebAssembly language
https://bit.ly/3NyZyr9
to improve support for functional languages.
