I have the same problem. Updated My FF and lost all my settings and tabs. I'm really angry. All my tabs are lost. I even tried this instruction , but backup files are empty. Also all my settings are absent. What is going on???

Why every time I upgrade FF I need to think would it work or I need to spend my time, to get my info back?

Always the same with updates. You think you're doing the right thing, but just a major hassle.

Hi, Firefox may have for some reason created another empty Profile; please see Recover user data missing after Firefox update

This solution doesn't work for me at this time. Next time I will try it.

Hi Scribe,

Thank you so, so much for your solution. Worked great and so easy even I could do it quickly!

Cheers, Christiane.

I had a Firefox update and i lost my bookmarks and I tried what they said on here to get thm back but its not working or I am missing something. Can anyone help with this? Thank You

This solution did not work for me - the Profile, the one in use and the only one showing, has no bookmarks. I have tried all the restore options as well - what's the next thing to try? Like many in this thread, I am hugely inconvenienced by this loss, and the time and hassle to repair it, and I haven't been able to repair it yet.
