3° deletion of Firefox

[karistan]

I’ve had enough! This is the third time Firefox has completely vanished! No more bookmarks, no saved passwords, no history of my recent windows—everything is gone, as if it were a fresh installation! Even my JSON backups no longer work!
I’m fed up with having to reconfigure everything every single time Firefox decides to change its layout!
It’s just like Windows 11—with every update, you have to spend hours figuring out a new system that’s supposedly designed to make things easier, but instead just makes them more complicated!
That’s it; I’m switching to Google. I don’t particularly like it, but at least it’s "stable."

@karistan : not sure why you're losing all your data between updates?

Is it possible you've had a new Firefox profile be created?  Tap the ALT key in Firefox to show the old
menubar, then click "Profiles" then "Manage Profiles".  If there is more than one listed, try logging into
a different one and see if your data is there.

You could also consider switching to the more-stable 'ESR' (business user) version of Firefox.  You can
download that here: https://www.firefox.com/download/all/desktop-esr/
