Rated 5 out of 5 stars

Exellent addon! Simple, fast and responsive.

Because of no proper alternative I was Tree Style Tab user for a long long time but it's too bloated and slow down firefox significantly (not just in startup time but also GUI reponse, changing tab). Tree Style Tab is more for power user.

I usually only have 15+ tabs on, tree management is nice too have but not neccesary, so this one is right for me.

Feature request:
- changing background color
- a toggle button to show/hide
- auto hide especially when fullscreen
Thanks!

Thank you for the review. Probably not in the next release, but I plan to include all three of your suggestions.
