Mozilla heeft versie 121 van zijn webbrowser Firefox uitgebracht. De browser, die sinds versie 116 minimaal Windows 10 of macOS 10.15 vereist, vraagt nu om de av1-codec te installeren wanneer deze niet aanwezig is wanneer hardwaredecoderen wordt aangezet. Verder kan de macOS-versie via stembediening worden aangestuurd en maakt de Linux-versie nu standaard van Wayland gebruik. De complete changelog voor deze uitgave kan hieronder worden gevonden.
NewFixed
- 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.
Enterprise
- Various security fixes.
Developer
- You can find information about policy updates and enterprise specific bug fixes in the Firefox for Enterprise 121 Release Notes.
Web Platform
- Developer Information
- 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 labeledPause on debugger statement
, located next to the existingPause 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.
- The
:has()
selector is now supported. This allows authors to match an element that has, or "anchors", at least one element matching its relative selector.- The
hanging
andeach-line
keywords are now supported for the 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, 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 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 to improve support for functional languages.
