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.
