"HAAAaaaaaaa..." (voix d'anges avec lumière divine venant d'en haut)
Voilà ENFIN une extension remplaçant convenablement les anciens groupes d'onglets disparus avec les persona.
Que son créateur en soit béatifié !
Plus sérieusement enfin une extension qui permet ET de trier les onglets par groupe ET de cacher ceux des autres groupes.
Merci merci merci merci.
Merci.
Merci.

edit:@Coconutsales:
TRY "open manage groups[STG plugin]" by Drive4ik
you can put it on the right.

Great Tab Group!
enjoy manage groups in Popup, Panorama, sidebar.
switch quickly and work well.
careful in many detail

Got so much on the go that I couldn't go back to living without this extension!

Does Simple Tab Groups supports Tab Session Manager? What should I do if FF suddenly crashes? Will Tab Session Manager restore all my tabs AND GROUPS?

Hey, thanks for making this app, it's very useful !

If you have some time, it would be nice if there was a way to move several tabs from one group to another or even merge 2 groups.

Also if you could implement a folder/file system where you can make a group of groups.

Great replacement for the old Tab Groups extensions! Wondering why is not shown as a replacement in the Tab Organizers collections along with the other ones. See https://addons.mozilla.org/en-GB/firefox/collections/4757633/tab-organizers/

Excellent add-in! I keep finding new ways to use it. Looking forward to see how it develops...

This is one of my most important add-ons, thank you very much for the great work. Browsing wouldn't be the same without it. Much appreciate your time and effort. Greetings from Germany

Transformational add-on when used with Firefox Containers. I am using about 20 groups for various clients and other activities. It makes organizing tabs much more efficient than having just one "strip" if you will. I absolutely recommend this add-on and thank to Drive4ik for making this.
