One of the most confusing interfaces, and most unpredictable interactions of any add-on I've used to date.

I created 4 tab groups -- social media & news; payments & banking; messaging; shopping cart. I populated each with several url's that I go to frequently. I created each group in a separate window and then selected the set of tabs and created the group. So far so good.

The next day I come back, I'm on tab in my shopping cart group which I had open and then select the group social media, which I had closed the evening before. It opens in the shopping cart group. Worse, it empties out my social media group, which is now for some reason associated with the shopping cart. So I have to recreate the group on new window and remove them from the shopping cart. Why? I have no idea.

Worse, if I try to move the tabs from my shopping cart by putting them in my original social media group, it tells me the shopping cart group is closed. Why? I have no idea.

This add-on seems so simple, yet, none of the features makes sense in its implementation. This could be a great add-on if it had any consistency. I'm still using it, but every day I have to reset one or more of my tab groups, scratching my head each time.

Consistency. This is not...

Have been using this addon for years. I currently have 1480 tabs across 28 groups (yes, I need to clean that up), but somehow this addon has not yet failed me. I do make occasional backups just in case. Great if going through sites with chapters/episodes that if saved via bookmark would become outdated. The management interface is easy to use, too.

Lost everything. Don't use.

I love this addon and have been using it for years. It's very useful for a kleptomaniac power user like me who keeps hundreds of tabs and needs a way to sort them. STG has its own backup function as well, which has saved me a few times when Firefox bugs and fails to retain its state. I also get the impression STG helps avoid Firefox getting overwhelmed and degrading performance.

My only issue is that it currently has no compatibility with the new native Firefox tab group function, which prevents STG backups from saving Firefox groups. Hoping that comes in a future update!

Best of the best app for saving work at current state as-is and moving to other work to find it in a state as it was. I'm convinced that 'simple' in addon name is eqivalent to 'good'

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.

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.
