Works flawlessly! My only complaint would be that it's a little slow to startup on HDD-based systems, and prevents tabs from loading content until it's finished "warming up" (which can take up to 30 seconds)

Not simple. It's hard to understand what it's even doing, aside from _definitely_ not what I want or expect it to do. The worst extension I have _ever_ installed, and I've installed some pretty terrible extensions. It's less than worthless. At least if it were just worthless, it wouldn't be a big mess to clean up after I uninstall it.

Excellent! It's a must-have for daily usage!

very counter-intuitive to use : if i wanted to group my tabs i want them in the same browser not in a different browser window

The most important addon to keep me in Firefox!

Needed to hop onto Firefox while Chrome was being a bitch, and this add-on allowed me to replicate Chrome's groups... somewhat. How to switch between groups took a bit of getting used to, and it's more helpful in some areas (i.e. creating groups) and less in others (quickly switching between groups). That alone would be a 4-star rating, but what drops it down is the difficulty of organizing tab groups in the groups tab. I can only organize it alphabetically, so I have to go through some hoops if I want my groups in a particular order, which is fairly annoying. All in all, a helpful add-on, if not exactly what I was hoping for.

gd, used for years

Nice extensions, allows to manage tabs much more easily. What I'm missing is ability to group tab groups together too - folders and descriptions for tab groups.

overall good but some minor issues exist such as problems with FB groups not being saved properly. Also the backup feature is completely broken. it ignores \ entirely so it keeps making new folders on the desktop instead of bakcing up where I want it to. been doing this all year

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.
