Forum der Gemeinschaft Firefox

I recently updated my wife's computer to an Apple Mac Mini M4 running iOS 15.4. Everything seemed to be working fine including Firefox until yesterday when Firefox update box popped up. She did as she normally has for years of using Firefox and clicked the restart for update button . FF restarted and popped up with 2 dialog boxes one asking to check network for there devices which she click "Don't Allow", she only uses that computer no smart phone etc. Then a second dialog box asking for an admin login and password to install something else I put in my admin login and password clicked continue it doesn't seem to do anything except lock up Firefox to the point I have had to re-install her user from a time machine backup 2 times in 2 days. I tried installing a new copy of Firefox that will launch the issue is she's used Firefox for probably 10 yrs so there are ten years of bookmarks and logins and passwords saved in the original copy of Firefox that will no longer boot unless I do a complete user re-install from a time machine backup.

Please help, how can I fix this problem?

I believe I am still using the first , I don't know. I am up to date. Does that mean I am running 2? I don't think, as I have 2 FF. symbols in dock(identical and conflicting I think). I tried to delete first version unsuccessfully and when I restart comp. from start I have to be prompted to set up again. My NordVpn account was doing the same tying with their Protection pro* (removed it- Ok now) . I have had FF #2 on comp. for a long time and I think I'm now just waiting to sign in now as I don't have FF PW-not problem. Making sure if I sign in to FF2 I won't loose my saved FF info... What should I do ? The SH. attached shows both FF's in desktop and Dock.Need guidance - Thanks a lot. Jon D.

I have a MacBook Pro running Sequoia 15.3.2. When I remove all data from Firefox (137.0 (aarch64)) in Manage Data under Privacy & Security there is one site datum that always returns. It is 64k of data, 0 cookies, that persists after every clean up. This has been going on for quite a while.

I've searched Finder for any reference to the company name and cannot find any reference.

It isn't a lot of data, but I'd prefer to not have something lingering around.

Does anyone have a suggestion for how to delete this once and for all?
