Fixed

Developer

The User Activation API has now been added, allowing JavaScript to use navigator.userActivation to check if the user is currently or has previously activated a page (click, etc.).
Early Hints Preconnect (message status code 103) is now enabled. This allows the server to send resource Link headers before the final HTTP response and improves the performance of servers that use this feature. ( More information )
Users can now simulate browser tabs offline using the new devtools feature.
A new "Pretty Print" button has been added to the footer of the Style Editor panel, similar to the Pretty Print button in the debugger panel. This button can be used to format the style sheet (such as a reduced style sheet). The previous feature was to automatically format minimized files, which has now been removed.
The "Rules" panel in the Inspector panel no longer displays hexadecimal/named colors in new CSS Color 4 formats such as OKLCH. This ensures a match with the original value used.

Web Platform

The lh and rlh units are now correctly parsed and calculated as lengths. This way, the author can specify the length based on the element's (or root element's) line height.
WebAssembly GC is now enabled by default, allowing new languages such as Dart or Kotlin to run on Firefox. To collect reference cycles between guest language and host browser.
