version 141.0.3 on a 2019 iMac 11.7.10 ... when this version was downloaded, bookmarks and history disappeared. Is there a way to recover or do I have to begin from scratch ?

hi there,

so i use tab groups extensively, for example I'm a freelancer working for many clients on many projects per client, so I open a group per project and have windows with stacks of groups and then just dip into the stack as needed for whatever I'm working on that moment.

Usually I'm good about closing firefox down so it remembers my tab groups the next time I boot (my mac OS Tahoe). However I was trouble shooting a piece of hardware that required me restarting the mac many times in a row and once it was all done about 6 restarts later, my windows with stacks of tabs were gone. Firefox had remebered some groups, but lost 70% of my tab groups, which is just a huge waste of time, I'm never going to go back and re-open tabs from months ago i.e. I can't remeber what i was browsing for which is why I save tab groups duh, so I just need this to be more robust.

Please write a big fat file of every group somewhere and make it recall the damn list on next boot, or 20 boots later. The only way it should delete a group is if I manually decide I don't need it any more and purge it from my library.

Just having the history is super useless, I'm not gonna waste more than 10 seconds looking at the thousands of tabs in my history trying to recreate my groups, just no way, I have to move fast I'm always on deadline.

Please and thanks!

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!

I have no idea why my browsing history, open tabs etc. didn't reopen after this restart. I previously had all the settings correct to reopen all windows after a restart, but now there's not even a history available.

The last automatic browser update (147.0.3 (aarch64)) has wiped off all changes I made to bookmarks and passwords from the past year.

How can I go back to a previous version and recover my details?

This browser version is terrible and looks exactly like Microsoft Edge which is not intuitive at all. I don't want to set up multiple personas, Its just me and the one computer?

Please help me. Kerri

Hey, So I just updated my Mozilla with the latest update and after I restarted my laptop all my bookmarks, history and favourites are gone. I didn't do any backups manually. It's few hundred important work-related links lost. What actually happened? Can I get them back? Please help.

My mac froze, force quit did not work, unplugged it, turned it back on, all bookmarks were gone and not able to add new ones. Would like to restore old bookmarks and add new ones.

i got an update message and restarted firefox. now all my saved bookmarks and passwords for accounts has disappearred. how do i get them back? under settings, it doesn't give me option to import from previous firefox

Firefox just updated and ALL of my bookmarks are gone. There is NOTHING. WTF? I am not a computer person so reading help articles just makes my head spin and of course I can't reach a real live person at Mozillabold text. Can anyone help?
