The latest update completely ruined my Firefox browser, lost all bookmarks and settings.

130.0 completely ruined my Firefox setup.  It installed and wiped out all settings, bookmarks, etc, I had.  Not possible to recover easily.  Do not know what happened to saved passwords.  This will be hell to reconstruct.  What have you done?

I entirely support this complaint. I've lost a substantial number of bookmarks accumulated over a long time. The new format has no way of recreating an organised list of websites, easily accessible on a side bar as used to be the case. Instead we have irritating rows of commercial rubbish on the screen and sites that need to be "dismissed" to tidy up the screen. Thei product now seems like rubbish compared with what it used to be. Very sad.

My machine (iMac) recently updated Firefox to 138.0.1 which deleted all my bookmarks, history, settings, etc, over 100 bookmarks and recent history.   Is there anyway to recover my lost bookmarks and history?   

I cannot believe Mozilla would allow an update this "effed" up to be released.  If I can't recover my lost bookmarks and history I'm switching browsers to something else.  Mozilla has a big black eye from this as far as I'm concerned.

Firefox decided to do some kind of update this morning and literally everything I have worked on for months is GONE. This is the SECOND TIME this has happened. Tbh I am absolutely livid... what the actual F is going on here?!?!? Are they f-ing stupid? This is disastrous!!

Same thing happened to me when I happened to close and restart Firefox 3 days ago (so not sure when the update that applied 142.0.1 was downloaded). On opening all tabs were lost. Fortunately I grabbed a session restore and got them back. Most of my browser settings were changed e.g Search Engine DuckDuckGo replaced by Google as default. Now I realise all my bookmarks (several years) are gone and my tab groups including all my most recent research. This is not the first time Mozilla has negligently damaged users with uncommunicated changes. I'm surprised this hasn't generate the storm the last one did. That one (private browsing behaviour) took weeks of hammering Mozilla in every forum to get the change reverted. And Mozilla never did apologise for the mess caused. I'm frustrated I probably don't have a useful backup for the most recent bookmarks - that's my mistake - but that doesn't excuse Mozilla for the bad behaviour. Yet again I'll have to look at moving to a browser with more reliable maintenance and more care for users. For an organisation and tool that have historically been of better service than most to the user it's sad to see that value lost by actions such as these. As ever the moral for users is trust nothing and backup everything.
