Did they COMPLETELY redo Firefox and not bother to warn us? "Alert! Save out your bookmarks" It looks totally different and I now have to log into a Firefox account?!? and select a profile?!?

Searched my C drive for BOOKMARKS found txt file with today's date...whew. Also found a .jsonlz4 file to restore from that was less than a week old. Dodged a bullet. This was the last straw though. Switching to Vivaldi.

The same thing happened to me when I updated Firefox. Also, wouldn't sync with the phone, so everything's gone.

So glad you found your bookmarks file, I'll go looking and see if I can find one, too. Then it's off to a different browser.

My comp BSODed on me and when I restarted the browser, wish I had worn the brown pants...no warning that the browser is updating to such a new version that EVERYTHING is going to be COMPLETELY different. Like swapping out a Toyota Camary for a boat....I'm done.

If you lost personal data then it is possible that a new default-release profile folder has been created. See "Determine if Firefox has created a new profile":

You can open the about:profiles page via the location bar to check whether multiple profiles are present and what profile Firefox currently is using.

Firefox 67 and later can use a dedicated profile for each of the Firefox update channels and will lock the profile, so it can only be used by Firefox in a specific installation folder. For Release versions this profile would be a xxxxxxxx.default-release profile, profiles used in older Firefox versions usually used a xxxxxxxx.default profile (a refresh adds a time stamp).
