Mozilla Firefox got a new monthly update recently, with minor new features, performance improvements and some bug-fixes.

According to the release note, Firefox 104 adds one more video site, Disney+, for displaying subtitles in the pop-out videos (Picture-in-Picture).

When the browser is minimized or occluded, and for background tabs, the UI will now be throttled for better performance and battery usage. And, paste unformatted shortcut now works again in plain text contexts, such as input and text area.

Other changes in Firefox 104 include:

• Support scroll-snap-stop and re-snapping properties for developers.
