Brilliant add-on. This is as close as I've come to Opera's workspaces (which I loved). This is even better though, as it combines grouped tabs with Firefox's containers. Also, if you're concerned that switching between groups is not just closing the current group's tabs and re-loading the selected group's tabs, then don't worry. They just show/hide tabs as you select different groups which is exactly what I wanted!

Please port this over to chrome..... I desperately need this on my brave-browser :/

This extension is just plain awesome! :-) Together with the "Tab Center Reborn" extension managing a huge amount of tabs is just pleasure. At first it takes a little bit to get used to it but after a while it's really fun. Many thanks for that great extension!

I can't live without this add-on now! It has revolutionized my browsing experience!!

the best tab extension for firefox.

good!

Great extension, probably the only one I found that had enough options to organize all my 500+ tabs and finally close them, while being able to archive them into a backup file, which I can still restore later on.
The behavior of "hiding tabs" when you add them into a group is a bit counter-intuitive at first, but you get used to it, and besides it's not really what I'm using the extension for, and I guess this saves memory.

An overall very polished add-on. Excellent work, and thank you !

Огромное спасибо за это приложение! Помогает как в повседневном использовании, так и в работе! Есть только один момент, который иногда напрягает. Я всё время использую pinned tabs и переключаюсь между группами вкладок в 1 окне браузера. Но, иногда, приходиться открывать 2-ое окно. Порой, я забываю, что открыто 2-ое окно (там нет ни групп, ни pinned tabs) и закрываю главное окно со всеми вкладками и pinned tabs. После этого уже закрывается 1-ое (почти пустое) окно и уже при последующем запуске браузера я больше не вижу своих pinned tabs. Это очень удручает... Может я что-то делаю не так, но выхода пока не нашёл, так как эти pinned tabs не сохраняются ни в какой группе и просто удаляются с панели при неправильном закрытии.
Но в целом, повторюсь, приложение отличное и, на данный момент, безальтернативное для меня. Спасибо ещё раз!

Es lo que estaba buscando, hace tiempo quitaron un add-on parecido que te permitía agrupar las pestañas como éste, al fin se recupera una gran funcionalidad

Love the fact that I can control groups with custom shortcuts and I can switch between them easily. This is by far the best tab management add on I've used. Chrome doesn't have an extension as good and customizable as this in my opinion.

I can't say how much I love this add-on. I've been wanting something like this for as long as I can remember. I have not found anything that comes close in the Chromium universe. I switched to FireFox for this add-on. I don't know why browsers don't have this functionality built-in.
