This helps organize my tabs while saving memory. It really works.

Moved to Firefox from Chrome. My old App (Tab Cloud) was not supported so I moved to One Tab. I am happy with the app, Had a small learning curve as I lost all my saved Tabs when I restored them. Found the options page and made some changes so this no longer happens. A very fast app that gets my mornings started off with all the web sites I check each day. I recommend One Tab.

great

Great extension ! Very useful and easy to use !

Highly Recommended!! Does Exactly what it promises... simple & effective. Love it!

Excellent idea and execution. By the end of the day I may have as many as 200 to 400 tabs open (many of which I don't need, but others which I do). This makes managing these so much easier. Nice work.

Great add-on, really do a lot help while this QUANTUM disaster ruined TMP.

the best addon! so useful!

It's because of IME, not browser or addon, sorry.
(X)Can not named the group...Ubuntu1404(x64) and FF57.

very nice

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.
