A must-have for Firefox users!

wonderfull extension, a must have.
The only thing lacking would be to have a "pin inside a group" feature ... (yes there's already pin out of it)

Thanks a lot! That's what I was looking for after switching from Chrome Spaces. Wish the developer and addon a long life!

Simple Tab Groups adds a degree of functionality and usefulness to Firefox which takes organising my research; study and the storage of such to a level far and away above that which is otherwise available. Fantastic plugin!

Great add-on. Would love the ability to sync tab groups between devices.

Loved it. Helps me a lot to organize my thoughts and avoid distractions
