This extension is probably the main reason I use Firefox. Almost every behavior can be changed and adapted to my needs. Thank you to everyone that made it possible, you make me happy.

good tree better than the firefox one

It looks good but how do I hide all the tabs at the top of my browser?

Definitely the most flexible extension at the moment!

The developers have created an incredible combine in terms of functionality!

Great app, so many configuration settings for customization; although unfortunately seems like not update for a year already.

Excellent and highly customizable plugin! I read that the version 5 (right now in beta) will have tab search as well. Can't wait for this! Thank you for this great plugin!

Edit after v.5 release: Just WOW!

Just amazing! Very clean and lots and easy configurations.

Great stuff, won't go back to regular tabs.
