Nothing 'simple' about this add-on. Confusing and over-engineered. Name change is needed...;)

Promettente, se non fosse che metà delle volte quando apro Firefox mi fa un casino e mi mette tutte le schede dei gruppi in una sola finestra. (io sono abituato ad avere almeno due finestre aperte durante la navigazione, sarà questo il problema?)

Meglio ricordarsi di fare un backup ogni volta alla chiusura di Firefox e ripristinarlo quando ti ritrovi un casino di schede all'apertura...

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)

A major drawback of this addon is that it forces you to hide the tabs that are grouped - as far as I'm concerned, this is not really tab grouping, it's more like a "fancy" bookmark sorter, only less functional and more annoying. I couldn't find a way around this problem yet. This is a disadvantage compared to the Chrome tab grouping - where your group appears as a single tab that can be easily expanded and collapsed when you want to show/hide all the tabs belonging to this group.

I think the UI needs serious work for this to be a usable tool. It also needs to work properly across multiple firefox windows. I did the mistake of installing this while having multiple tabs on 2 windows and it was not a fun experience.

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

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.
