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

This is insane

I love this add-on, helps me a lot tiding up all tab mess during study. Students, researchers, developers definitely must use it. Saved a lot of time when switching between work and study tabs groups. Everyday you use it more, more features you look for. I would like to see a nice keymap built around it then I could do magical gestures without going to mouse. tap! bam! posh!! tabs are archived and I created a new group in 3 seconds, wicked!
