I don't know why anyone would use this. Does not reliably save tab groups.

keeps crashing when trying to restore backup. tab groups load but not the pages in them.

Одного чудового дня пропали усі вкладинки, не рекомендую нікому у кого є до праці 10+ вкладинок

Unfortunately, the add-on no longer works with the current version of Firefox.

К сожалению, дополнение неисправно. При попытке восстановить группы из резервной копии, браузер просто падает и восстанавливаются пустые группы.

Hopefully mozilla get around to removing apps from the store that mimic existing built in firefox functionality. It's likely a fact that these tab group extensions predate the firefox addition, but that isn't the point. They are essentially obsolete now and none of them that I've seen seem to add anything unique that firefox doesn't, and the built in seamlessness just works better anyway. These extensions (not limited to tab groups ext.) are populating the store, negatively impacting navigation experience and ext. search relevancy. A mild inconvenience to complain about, but a mild inconvenience to fix it too, so just do it. These extensions seem to be prevelant, and are even taking up the bulk of my mozilla "recommendations".

Simplesmente NÃO funciona. Gastei mais de 3h criando grupos, mas a extensão SINGLE TAB GROUPS simplesmente não grava os grupos que criei e os apaga sempre.

Nope, great Idea but every some updates it kills everything and is not relaible. Now lost 200 tabs ....

All open tabs that were not in a group suddenly disappeared, as I was managing groups. They only reappeared again when the extension was uninstalled. That's a terrible user experience. Avoid.

Lost everything. Don't use.

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.

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...

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

why is this "recommended" by firefox exactly?

ADD DARK MODE COMPATIBILITY THATS EASIER TO TURN ON

Unreliable at best. I don't consider any application worthy just because it works "sometimes". This extension repeatedly dumps all your tabs thus requiring you to restore them. No company in the world would put an application into use that was that unreliable, nor should you.

I don't understand the apologetics of those who think that just because something works sometimes, that it is still a worthy product. That is garbage and complacent thinking.

The application randomly and very frequently deletes all tab groups without warning.

It also creates back-ups but dumps those back ups in your download folder but it does not provide a mechanism for you to choose a more appropriate location.

So be prepared to have to restore your tabs from those back ups every few days. If this kind of silliness is "ok" to your thinking that's your business. But try that with Photoshop or the program you use for your personal finances. I imagine you would think differently.

The extension is not reliable and should not be trusted for use with anything important. You will lose data.

Legit kept hiding my taps and I couldn't make groups show on the tab list

Keeps loosing my tabs when I close firefox.

First time using. Had two separate FF 136.0.4 (64-bit) instances open with multiple tabs on Win 10 Pro, up-to-date.

Created a new group, made a typo and deleted the empty group. The main instance containing the tabs (over 30) I wanted to group closed and isn't recoverable, two days of research down the drain.

And now I need to find an alternative.
