Exactly what I needed, thank you

Extremely helpfull Add-on. Helps in any kind of research or just by sorting the 20 tabs you have open. The only thing that is missing, is the option to save tabs with the hirachie. That would be super helpfull, if you want to continue your research later.

This add-on saves my web life. It is the only reason that I use Firefox!

Awesome!

I have been using this extension for years and I must say it’s the best tab manager I know. There is nothing at the moment on Chrome which works nearly as well as Tree Style Tab does on Firefox (lack of native Sidebar maybe?). Use together in combination with the other addons that extend TST for the best experience and productivity boost!
