Works flawlessly. Essential when working with multiple tabs open tabs on projects with multiple aspects. Tree level management saves a lot of time, keeps active tabs organized, and helps avoid closing tabs still in use by accident.

Best addon i found.
For multitabs.

ótimo aproveitamento.

Great extension
Help me in tracking my mess while surfing around.

Just to make it clear, this plugin is the reason I came back to firefox ! THANK YOU for creating & updating it .

Wow, this should become a default for FF browser, I could never ever work without it. Helps my productivity and reading/working style a lot. I can only recommend it.

Nuts...doesn't work with Colorful Tabs like it did in the old Firefox.

Amazing features, but glitchy. Especially when I have two windows open using it. Tabs get sorted weird, especially on restarts, sometimes phantom tabs (that aren't selectable but show up in the menu) linger, tab order gets screwed up, etc.

I find this a much better interface than the tab bar. It's not quite as nice as the old version of the addon but I think this is about as good as can be done with the new WebExtension model.

I love this Add-On... use it and abuse it...
It does take a bit of practice and learning, but it sure works for me...
Only thing I hate is... I can not get rid of the Tab Bar at the top of the browser...I see no point in having it there....
Is there a way to turn it off?
