Mozilla recently released firefox 81’s first maintenance update. One of the most important aspects of this update is to fix a high memory footprint issue that was first reported in Firefox 78 and has been around for two months.

Users who reported feedback to Mozilla on Bugzilla explained that the issue made Firefox completely unusable. “Firefox crashes, performance is chronicly unstable and unavailable,” he said. Firefox does not offer a demotion to 77 in a way that is constantly harassed on a daily day. I want Mozilla to provide a non-harassment build, preferably a security patch.”
Mozilla says the new Firefox update also addresses a picture-in-picture issue that causes the control to become visible on audio-only page elements. The problem was first reported nine days ago and was discovered in Firefox 82 beta 2 and Firefox 83 Alpha 1, but Mozilla found that the latest browser stabilization on Windows, Ubuntu, and macOS was also affected.
