It is extremely useful, stable, easy to use.
I have been using it for four years now without any problems.
It can also create backups, which take almost no storage space.
Also fully open source and recommended by Firefox :)

- it completely destroys the parent/child/sibling tree structures managed by Tree Style Tab
- it's rather slow and rigid compared to the panorama view that was possible before FF 57
- there seems to be no way to quickly ungroup / separate tabs without defining a new group
- i think that it could be a lot more minimalistic and faster at its core, and at the same time more intuitive and flexible when needed

Before this plugin, it was a mess to manage different windows between different contexts. Thank you for developing this fantastic extension!

I really like this extension a lot and being able to separate my work/personal/school stuff into different groups, and being able to pin frequently used sites as tabs is awesome. But I do have one big gripe, which is that whenever I have to close or restart my browser for any reason, and I go to reload my last session from my Firefox history, all my tabs end up in the "Other" tab group and I have to drag them all back into their proper groups.

I'm not sure if there's some setting I have wrong or that I didn't enable or what, but it's a major annoyance and hassle, especially being someone who often has 50 or more tabs open at once most times, as I don't think I can select and drag multiple tabs at once in the group manger and have to do them individually. I'm glad all my tabs are saved and all, but I feel I should be able to reload them WITHIN their actual tab groups.

The extension itself functions as it should, the only take away is how I'm not able to switch groups while in a google meet as it uses the mic and camera. The reason I downloaded this is to separate my school stuff from my personal stuff.

Does not work like the grouping of tabs in Chrome. This is a very counter-intuitive add-on. Don't know why it hides tabs that are not in a group. If you remove tabs from a group it just closes the tabs. If you have a group open and open a new tab the tab is automatically added to that group. Nothing works as I would like to work.

cool

This is what I needed from many years ago and finally I found it!

Very good add on. If only we could have seamless integration and synchronisation with Sync one day that would be great.

My only big concern with the module is that when the backup to a tab bookmark folder kicks-in, it messes up my tab groups folder (tab groups appear twice).

Also for some strange reason when I manually rename the folder and move it elsewhere so I keep an archive of my older sessions for safety they always get messed up (most tab go missing) with time.

Though GREAT add-on for Tab addicts, when you adopt it you will never want to go back!

Wanted something like Chrome's grouping function and this is NOT it. Has built-in containers that cannot be modified and is terrible to use. Managed to lose a complete session due to how badly it is designed.

The most necessary extension for Firefox. It works very well until version 86.0.1, but it is "breaking" in version 87, consuming all the memory and crashing the browser. Even so, I prefer to use the old version of the browser and keep the add-on installed, but correct that, please, I would be very happy. Congratulations to the developers!

I don't get it, this thing is very counterintutive to use. I send a few tabs in a new separate group and they still appear under Hidden Tabs. I remove them from the Hidden Tabs folder and they also disappear from their new group. I restore them, open the new group and everything else disappears and goes to Hidden Tabs. This is not what I want. I want to have my rogue tabs open and always accessible, AND groups of tabs I can launch at will. 2/5 is probably too much but I'll be lenient.
