Exactly what I needed, thank you

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!
