I-Firefox Community Forum

Whenever my laptop starts up,firefox with all of my tabs always starts up with it. When i rose up earlier in the day and started up my laptop firefox with all my tabs opened up as normal,but this evening everything is gone. I had at least 20 tabs open and they were all important. There was no option to recover the tabs and this isn't the first time this has happened,this is at least the third time that this has happened after the last year and a bit. This is incredibly annoying and frustrating. Is there even any point in asking the community how this can be resolved?

SUBJECT: Profile missing after update to 146.0.1 

After the last Firefox update (146.0.1), I can no longer access my profile that included bookmarks, history and passwords.  

After the update was done on 12/19/25, I was given the option to choose between my original profile and a newly created one. The next day when I opened Firefox, there was only one profile shown and my original profile was gone. I have read numerous fixes for this problem but nothing seems to work.

I have done the following to try to locate my missing profile to no avail. 1. I went to the Profile Manager but the only profile listed was the newly created one. 2. I didn't do a refresh so there was no "Old Firefox Data" folder to copy the data from. 3. Used about:Profiles, Again only the newly created profile was listed 4. I used ~Library/Application Support/Firefox/Profiles. Still no luck. 

Could my profile have been moved to another place or could it be hidden? Any help would be greatly appreciated!

For some reason all of my bookmarks are gone. I have tried all the suggested fixes and it's still not working. Don't know where they went but I would sure like to have them back. Plus, now when I try to bookmark a page its not accepting it. :(

I've tuned in to Firefox this morning to find that I'm kind of shut out, no access to my usual apps, and required to enact some difficult backing up etc. When I explore, it seems to relate to Windows 10 losing its backup from Microsoft. But I'm running Windows 11, not 10. What's going on? Is this legitimate? If so, why is it complicated and why wasn't it forewarned (by Firefox)?

Firefox recently started asking for a profile when I tried opening a link from email but, not having a profile, I ignored it. If I copied the link into my firefox browser (already open) I could see the link contents, i.e. page(s) opened. Since then I have closed Firefox and now get asked about a profile and have tried using original and creating a new one. We have, unfortunately, reinstalled firefox so this is now more complex. At present, whether I login to Mozilla account or not, my passwords, history etc are no longer on my laptop, despite supposedly being connected. Firefox on my phone is currently the only source of my passwords etc, which is not good as I cannot export from there!

Can I restore this info somehow? We've tried a few suggestions found on the web, but no good yet.

Has something changed recently? My husband got the same profile request on opening Firefox but it worked when he selected use original/default profile.

Firefox deleted many folders in my bookmarks file. Then, trying to straighten this out, Firefox has completely changed its home page layout and I can not manage it even in the simplest way. I want to restore everything to how it was two or three days ago.
