If you try the steps in the first section of the following article, are any other profiles available: Recover lost or missing Bookmarks?

Is there any way to do a global search for a profile folder file such as places.sqlite?

Hi there

I've tried that, however looking at both available profiles my previous data is no where to be found.

Firefox has just written over my profile, no matter which profile I choose none of my data is there.

My laptop which has the exact same setup updated fine 😒

I've just found my profile in the snap package directory, I've now configured my apt/discover utility to favour installs from Mozilla instead.

Why it failed on this machine I have no idea, everything is back as it was.

Thank you

As a Windows user, I'll just smile and pretend I understand that. ;-)

But seriously, did your system's app updater somehow switch from one type of package to another overnight? That could wreck a lot of peoples' day.

Lol I'm used to Windows myself but dislike Windows 11 hence the switch...

It certainly seems like it decided to switch from Snap to regular *.deb installs

I'll keep a close eye on it, at least I know what to look for in future. Oh and to stay away from Snap packages haha

Thank you for taking the time to reply, really appreciate it 🙏

I don't have Linux, I have Windows 10 - and none of the solutions I Googled, or listed above helped me. Still can't find my old profile (before the update yesterday). I don't find an "Old Firefox Data" folder anywhere.

Any suggestions?

Thanks, Jean
