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!

This extension is one of the main reasons that keeps me on Firefox. If Firefox didn't have this, I honestly don't know which browser I'd be using ... but, in whatever case, I would be a sad little monkey! If you use more than 5 tabs, THIS is the way it should be!

Great extension in the very "limited" new Firefox. Thank you!!!

Works perfectly (nonobstant les pertes de fonctions dues au changement du moteur de Firefox, ce qui est indépendant de la volonté de l'auteur) !

For those who would like to hide the native tab bar :

- toolkit.legacyUserProfileCustomizations.stylesheets to true
- create or edit the “userChrome.css” file and add the following :
#TabsToolbar {
visibility: collapse;
}
