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

Most great! Only thing missing IMO is a shortcut to open Simple Tab Groups in Sidebar (i.e, not having to multiple click to get to sidebar). Otherwise, great - thanks!

Spesso le schede dentro un gruppo si duplicano/triplicano senza motivo

Addon popped up a page stating it crashed or something or other and requested me to load a backup. Doing so made me lose countless windows and tabs that just so happened to not belong to any group at the time

Omg do NOT use this extension. I really do not understand why it has so many starts. Needlessly complex as another reviewer has stated. I grouped some tabs, then opened that group and it cleared my entire window of the tabs I was using! Unbelievable. Who in their right mind thought that was a good idea? I had to disable the extension to get them back. Stay far, far away from this extension if you value your tabs!

Lately my browser is freezing up so much.

Was great till it started to load so slowly that it took over my browser completely for 10+ minutes.

This is insane
