All Firefox versions have been simultaneously updated, with Firefox Beta and Development now advancing to version 125, and Firefox Nightly also making strides forward. The Android version has been synchronized with the desktop release, reaching version 124 concurrently.

Summary for Executives

• Firefox 124 primarily concentrates on bolstering security measures.
• There are several fresh additions and refinements, including the introduction of caret browsing mode within the PDF reader.
• Mozilla appears to have resolved the issue of “all black” thumbnails on older AMD systems.

Firefox 124.0 Installation and Update

Updates for Firefox are typically automatically handled, and version 124.0 is slated for automatic installation on most systems. However, real-time updates may take a bit of time to propagate.

Please Note: This overview is being published prior to the official release. Updates will be accessible later in the day upon publication.

To manually trigger the update installation, users can check for updates promptly by navigating to Firefox Menu > Help > About Firefox.

Modifications in Firefox 124.0

Firefox View: Improved Tab Sorting

Firefox View, designed for managing tabs and activities, now offers the capability to organize open tabs based on their order rather than their activity recency. This alteration enhances tab organization by aligning it with the tab bar’s tab appearance sequence.

Additional Adjustments and Fixes

• The Qwant search engine is now accessible in the France region alongside several other countries.
• The Ecosia search engine is now supported in Germany as well as various other regions.
• Caret browsing mode has been integrated into Firefox’s native PDF viewer.
• Improved population of the jump list in Firefox on the Windows taskbar to enrich the browsing experience.
• Enhanced utilization of macOS fullscreen API to enhance user experience on macOS systems.

Developer Updates

• Introduction of support for AbortSignal.any() for enabling cancellation of operations from multiple signal origins.
• ::first-letter and ::first-line CSS pseudo-elements are now applicable to the <text> SVG element.
• The runtime.onPerformanceWarning event signals extension developers about runtime performance concerns.
• Inclusion of support for SharedArrayBuffer growable and resizing ArrayBuffer (activate through configuration settings).

Enterprise Revisions

With Firefox 124.0, Mozilla has introduced a new policy and updated an existing one:

• New ‘AllowFileSelectionDialogs’ policy for managing file selection dialogues within Firefox.
• Enhanced DNSOverHTTPS policy to enable configuration of a fallback value to prevent default DNS provider fallback.

Future Outlook

Looking ahead: Firefox 125 and Firefox ESR 115.10 are scheduled for release on April 16, 2024.
