Firefox Community Forum

I lost all bookmarks on or about June 29, 2026 after doing a Firefox update that asked me to create a profile when I'd never had one before. I have not been able to recover them.

For some reason firefox uninstalled on my computer, I genuinely do not know why. When reinstalling it, I have an old save from my backup of that morning (I have it setup that way). However, I do not remember this password whatsoever and I am freaking out a little bit since I have information on there and I am just trying to get it restored onto my account.

Any help would be appreciated.

I have to reload history, bookmarks, passwords each 3 - 4 days, when Firefox refreshes the software. It was not happening before, just in the last two moths. How can I fix it?

I have been using Mozilla Firefox on my mobile phone or PC since 2015. So, after so long, I found the Gmail that I used to log in to Mozilla from 2015 to 2018. Now, if I log in with that Gmail, will the previous history or data be restored or will it be Mozilla's?
