FINALLY A PLUGIN REALLY THAT WORKS!!! As a web developer, I have like a million tabs open at the same time and this feature is a MUST HAVE to allow me to group tabs! (I started grouping tabs before Firefox added the feature, so I move to firefox feature, then they removed it and I started using a plugin but It stopped working .. was missing this feature untill now)

This is a terrific, must-have add-on for researchers and people with busy, creative lives. As a researcher, graphic designer and IT professional, I am often involved in dozens of projects at once and it's not unusual to have dozens of tabs (often several dozens) for each project. This add-on allows me to segregate them into logical groups and call up and use just the group I need, organized the way I want.

In locating parts and ideas for building a custom PC for a client, for example, I may open and use dozens of tabs; with this add-on, I can keep them all grouped under the client's name and share them with the client.

I work with Adobe Illustrator a lot; with this add-on, I can organize the pages, tutorials, online graphic resources, etc., in logical groups, available at the click of an icon. These are just a couple of examples; I have over 25 such groups right now.

I was using Tab Groups by quicksaver (a thousand thanks to you, my friend!) and actually stopped upgrading Firefox at v54 so that I could keep using this essential (for me) functionality. Glad to finally find a worthy successor to that add-on so I can keep working the most efficient way for me! I can hardly recommend this add-on highly enough!

im totaly excited having this add-on. it just does what i need. stable, nice, easy to use. i followed the dev from the first day, it had had all of those bugs, growing to a "version" i trust in for my daily shit i want to do with it. thanks guys .. realy appreciate what you've done so far. thanks! happy to support were ever i can...
for the negative comment from jonnoN some days ago:
"Unloads tabs that are not in the active group. Want to listen to music? Too bad! Useless."
--> mate, just pin the tab you want to listen to and it stays active. ... don't rate it bad for that, please

Working good so far. Good replacement. Any chance that at sometime in the future tabs opened in one group will stay open when you switch to another group like they did in pre-Quantum extensions?

I do love this add-on. However, if you are adding this to an already used window with multiple tabs, you should make sure to add ALL current tabs to new groups BEFORE you attempt to switch to a new group. I lost a few hundred tabs and using History, spent two weeks trying to re-find those lost tabs. A good idea for multiple tabs would be an add-on similar to "Copy All Tabs Urls WE" 1.0.4 By Michele Pezza - at least you won't lose your tab's addresses.

Awesome! I was missing Tab Groups.

I missed old Tab Grups :)

Step by step I retrieve "Tab Groups" module's features.
Very useful module, thanks!

Great!

brings back functionality of tab groups

Thank you, you saved me :)

This add-on makes it up for the native tab groups being gone at the latest versions. The only issue I have is that when closing tabs (I got 200+ tabs open and need to close/organize them) at the bottom of the group, it scrolls up again after closing a single tab. I wish it would stay scrolled where is was. Hope you will fix this. Otherwise great add-on.

Wow this is what I was waiting for
