(Bug 1869994) https://bugzilla.mozilla.org/show_bug.cgi?id=1869994 Fixed Firefox not closing properly and other applications being unable to use a USB security key after being previously used during a Firefox session. (Bug 1863135) https://bugzilla.mozilla.org/show_bug.cgi?id=1863135 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. https://bugzilla.mozilla.org/show_bug.cgi?id=1621261 https://bit.ly/4am7Exf https://extensions.gnome.org/extension/4691/pip-on-top/ Firefox can now force links to always be underlined. This option can be enabled in the Browsing section of the Firefox Settings menu. https://i.imgur.com/torhTom.png The PDF viewer now includes a floating button to simplify deleting drawings , text, and images added in PDFs. https://i.imgur.com/UYhCkjC.png Fixed︰ Various security fixes. https://www.mozilla.org/security/advisories/mfsa2023-56/ Enterprise︰ https://support.mozilla.org/kb/firefox-enterprise-121-release-notes 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. https://i.imgur.com/024Z5dE.png 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. -- 身在黑暗 心向光明 --
