Private mode is NOT SUPPORTED. What a bummer!

this is very good, but my only complaint is that I have to re-sign into everything in the tab groups

A must-have for Firefox users!

The absolute worst thing happened to me! I tried to open an old tab in a group I that's never been opened for months, I checked Task Manager and Firefox went from 5gb memory usage to over 20gb and it just kept increasing until my PC stops responding. This memory bs happened everytime I try to open Firefox, so I had to uninstall Firefox and lost everything.

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.
