Perfect to organize all your tabs

Has served me reliably for years. However, it recently began to fail in downloading auto backups, clogging up my downloads menu with these "auto-stg-backup-dayofmonth..." errors. Not sure how to contact the creator about this.

When it works, great extension. Can't close Firefox though as I always lose my tab groups. When manually restoring from a backup, Firefox will just crash. I end up trying several backups before one finally loads my tabs, and of course they're not the exact ones I want.

Worked well for a time, then deleted all of my tab groups, and neither my manual nor automatic backups were saved.

This is by far the best tab grouping app available. It offers unmatched flexibility and customization compared to anything else on the market. Unfortunately, it’s been broken for months. Even when I manage to get it working temporarily, it often loses my saved groups or fails to restore them properly. The restore feature is inconsistent at best.

It seems Firefox updates may have caused compatibility issues, which is understandable, but I wish the developer had continued maintaining it. This app is leagues ahead of Firefox’s recent native tab grouping, which feels limited and clunky by comparison.

I’m holding off on uninstalling it because I still hope for a fix. The moment it’s stable again, I’ll gladly update my rating to 5 stars.

Almost everything I could possibly want, and it almost brings Firefox up to parity with OperaGX's workspaces (though it surpasses it in others). Almost.

Pinned tabs and Firefox's native tab groups tend to 'leak' (for lack of a better term) through the groups in this extension.

Unfortunately no longer working with Floorp browser version 144.0.2@12.3.5

I was loving this, until I lost all groups when coming back to work today, all was fine Friday... I'll try redoing them, and after looking in options I saw there are backup/restore options, I hope it works, else I'll have to fine something else.
Edit: finally I saw there are automatic backups and was able to restore last one, give 4 stars, not 5 that would have been if I did not lost all groups in the first time.
Edit again: I should have looked better, yes all my groups have been restored, counters of tabs seems good, but there are missing tabs, when I change group it just jumps to a tab keeping others (from other groups) open, and do other weird stuff... And now its even worse that before I restored... Too sad...

Basic functions work: in management mode, drag & drop one tab list item to another group; switch to group. The biggest problem is memory usage after long time usage of Firefox v 143 on a Mac Tahoe (not sure of other OS). The memory usage jumped from around 1GB to 7GB after upgrading MacOS to Tahoe version. In the background, must be keeping other OLD tabs in groups already closed but still open (not sure contents of pages already loaded). When I disabled this extension, suddenly more than 20 tabs popped out when total opened tab in all groups were about 7. Plus, Firefox now has implemented tab grouping feature same as Chrome: to collapse tabs into 1 group tab.

Very easy way to decrease the number of open tabs.

It was good extension, but today all my tabs in groups are gone (except main group). And i have no backups to restore

i keep having issues with previous session not opening, and normally i can just click "restore previous session" and it returns all the tabs to the correct groups but i had a guy clean my pc today and he didn't restore session before closing and reopening again (which makes the option dissapear). which left me with "reopen all tabs" in recently closed, and not only did it not restore them all, they were not in groups after restoring. well, the extension only made the experience slightly worse but i needed somewhere to vent i guess lol. becareful out there if you cherish your tabs
