Firefox 117 browser out with new features, but some beta features left out or disabled by default

Mozilla Firefox has released Firefox 117 web browser prior to its official launch on August 29th. The final release, however, doesn't include certain features from the beta version, either omitting them or presenting them as disabled by default. For instance, the privacy-conscious translation engine introduced in the beta version, can be enabled through about:config, with plans for it to become the default setting in version 118.

The update also includes expanded credit card autofill for IT, ES, AT, BE, and PL locales, enhances YouTube video list scrolling for screen readers, and a new setting that allows macOS users to control tab-key behavior. For Linux users, the screen-sharing indicator on Wayland systems has been eliminated due to its ineffective functionality and redundancy, given that Linux desktop environments already offer sharing indicators. The new dom.event.contextmenu.shift_suppresses_event preference in about:config allows users to disable the context menu enforced by the Shift+right-click shortcut on web pages.

The Android variant of Firefox 117 now facilitates pasting images into content editable and designMode elements, alongside plain text and HTML content. Web developers can leverage improved CSS nesting support by default, RTCRtpScriptTransform support, ReadableStream.from for creating streams from async iterables, and new CSS properties such as math-style, math-depth, and font-size: math. The web compatibility inspection has also been improved with a CSS compatibility tooltip in the Developer Tools Inspector.

Firefox 117 can be directly downloaded from Mozilla's server, but users with distro-installed Firefox should wait for repository updates.
