Pratique si on a peu d'onglets et peu de fenêtres. Car au lancement de Firefox il charge la fenêtre courante mais aussi toutes les autres fenêtres "cachées" ou groupe d'onglets. Ce qui ralenti le démarrage de Firefox qui peut utiliser rapidement plusieurs Go de mémoire. Toutes les fenêtres masquées devraient être libérées ou ne pas être chargées dans la mémoire, si on les utilisent pas.

Exemple, 15 groupes d'onglets avec environ 100 onglets au total chez moi.
Chargement de Firefox : en ouvrant une seule fenêtre, 3300 Mo mais c'est surtout le temps de chargement qui est pénalisant.
Avec un autre addon (auto discard tab) je décharge toutes les autres fenêtres, utilisation mémoire tombe à 700Mo c'est plus logique.

This addons is amazing. I can create a group for every work tasks which keeps my browser organized and I don't have to search for specific tabs from dozens of open tabs.

This is a smallish thing, but I wish that when you open the tab groups list, the selection would jump to the current tab group (instead of having to scroll the list to see which group name is highlighted)

I also wish I could rename tabs. (I know there's a separate addon for that, but I'd rather have one plugin that does it all)

complete crap, didn't get the small 3x3 square icon on my toolbar like in the example images. no way to add it either as far as i've been able to tell. additionally this extension randomly filled the first available group(s) with my giant old bookmarks library. something i never asked it to do. which resulted in that when opening a single group in testing.
after finally having found something to access a group i made (to get my tab back), this junk immediately floods my browser with countless open tabs it also stuffed in there...

i can't understand... how difficult is it to just group up a few open tabs/pins into a single tab/pin like asked, then have this single tab show the grouped up tabs. like several other browser do already these days... it's not rocket science yet one of the few things FF sadly doesn't have, but this extension certainly doesn't help with this either...

thank you Drive4ik

Very unintuitive and hard to use...

Ne fonctionne juste pas, que dire de plus ?

Total Dog/SH!t. Just spent 30 minutes at least organizing tabs. Installed this plugin. Its totally non intuitive and absolutely sucks. Restarted Firefox, and I have like 50 organized tabs closed that I never even added to this garbage add-on. Absolute trash.

Develop extensions, it's important because Firefox doesn't have extension grouping, hopefully it will be lighter and work faster, without crashes, and new features, thanks.

it's nowhere near perfect, but it is far better than the few other extensions for this kind of workflow. if you work on it a bit you can get it to do what you want.

DO NOT DOWNLOAD. WORTHLESS EXTENSION ONLY RUINS YOUR TABS. Developer: are you dumb? Why did you create this worthless extension? Do you know how much research I lost in trying to use your stupid extension?

This add-on simply become must have add-on for me.

Not sure why so many reviews are saying this is hard to use. I found it easy and simple to setup and start using.

Not simple.

As other 1-star reviews have stated, this app is counter-intuitive and not very helpful. If you are looking for something like Chrome's tab groups, this isn't it.

Spent an hour or two trying to figure this out. It ain't simple. Nearly lost 30 tabs I had open. Add-on had hidden them. Once I found them I had to move each tab individually (never heard of select all?) to get them in one window/group before I was confident I could delete this add-on. Instead of saving me time, it's wasted much of the morning.
