This is helpfull and simple!

Believe me, This is the best tab groups manager so far.

Amazing add on, simple to use without any troubles.

best add on for tab groups replacement so far

Thank you so much! A great replacement for the old Tab Groups I agree. This means I could finally update FF on all my computers. You, good sir, are a godsend. Great work!

Almost perfect replacement for the old Tab Groups that was destroyed by Mozilla. Only lacking sidebar support, so if you use that, be aware.

first impression:
nicely done :-)

Really great addon! Thanks for keeping Firefox going!

Development now advanced far enough for this add-on to be a reliable replacement for the old tab groups extension, but latest version drops ability to denote current group through color of toolbar icon--an inconvenience.

Finally a really good alternative to my old tab groups. It's optically pleasing and I didn't discover major flaws yet.
One minor error though: When using the Amazon fav icon as a group icon (right click on tab > set icon for group) it does show up on the usual STG icon but not when I click that icon to show the group overview. There it will show a not-found-icon. So far I could only reproduce this with Amazon (GER).

It's the first time I even bother to write a review. This is the best tab management tool and I tried tens of them. It's even better (simpler and faster) than the original one it's mentioning as inspiration.

I've been using it for a few days now and didn't see any bugs.

5 stars for the superb effort in getting this add-on up to par with the old Tab Groups (and surpassing it in some ways)! Must have been a huge challenge with FFQ, I can imagine. I use tab groups every day for work to help keep everything organized. Don't know what I'd do without it. Keep up the great work!

The best!

Thank you, I looking for add-on like this

It makes the life of a Web developer a lot more productive.

Can't wait to see what future improvements will bring us. :-)

Wow, finally on FF Quantum (FF61, 07/2018): we have old good Tab Groups and even better and more customizable. I like custom icons for groups - very handy. Thanks, developer! <3

Finally, a fully functional replacement for the good old TabGroups!

After the last release, the tabs are finally not reloaded after switching groups. Taking into account the limitations of the new API, this extension deserves 6 stars.

Thanks Drive4ik! Now I can use Firefox just like I used to before WebExtensions era.
