Really useful! I love it!
(My only complain: it doesn't on Firefox 57 for Android)

Great addon. Very usefull. I backup the list of urls now and then to be safe, but it works fine for me.

It could use more user friendliness like shortcuts for more actions or more options to arrange the urls in the list and behavious of the groups.

Please cooperate with these guys, gestures would be very usefull.

Extensão muito boa, uso a toda hora e me economiza memória.

Boom

I just clicked the button while watching Resource Monitor, my used memory drop by half. I think i'm in love.

This is one of my all time favorite extensions; on both firefox and chrome.

I think this is a great replacement for Tab Groups (the original Firefox version that was deprecated and the great add-on by Quicksaver that has gone extinct).

I wish we could click to drop down the icon on the toolbar to switch between named groups like we could in the Quicksaver version. The ability to save the entire set dynamically (without having to import and export) and switch between them like with Session Manager would be awesome as well.

The context menus are great and have a lot of options for grabbing sets of tabs to add to the list.

I did not use this add-on in FF56, so I can't speak to the upgrade path, but it seems as though they have instructions to follow for downgrading.

正好是我想要的功能

The best tab managing add-on, bar none!

Useful

Nice design and enhencement of tab groups.

Thanks for update for FF Quantum =D
