This is the best way I know to manage my tabs. It is absolutely excellent with lots of features.

I can't imagine a life without this addon. Thank you so much Piro.

Fantastic! Thanks!

Great extension for any multi-tasker, end of story.

This extension is absolutely essential for doing research, looking through programming references, and general reading and browsing. I don't remember what I used to do without it!

If you open lots of tabs, then TST is a must! No other browser or add-on can manage your tabs as easily or efficiently. This app is the reason I use Firefox over any other web browser ^_^

This extension is the USP of Firefox and the reason I still use this Browser! Thank you so much Piro (piro_or)...

Tree Style Tab is my first reason after security and privacy to use Firefox. I really can't imagine browsing without such an extension. Great job, Piro!

the best tree style tab extension I've tested so far!

Switched back from chrome to firefox just to use this addon. Very valuable, great way to organize tabs for people like me, who have multiple sudden ideas scattered around and like to group those ideas in tree styled tabs. Too bad it's a bit glitchy lately - sometimes child tabs don't want to be attached to parent - for some reason they appear in different places, yet they seem to be still related. Reopening browser helps.

Thank you for this addon!
