You mean besides the forced update? Unfortunately not much I can help with, in my case I was deliberately running ESR 78.14.0 which was force updated to ESR 102.11.0 on May 26 and later 102.12.0 on June 20 (setting is obviously 'Check for updates'). It was a pretty big change first, so I naturally tried to revert back as much as I could. However for example Google Image Search is broken again, clicking it simply crashes the tab (Gah. Your tab just crashed), which could be fixed by tweaking some options in the earlier version iirc. Unless moz://a managed to break it a different way this time
