No permission asked = 11/10 or an easy 6 star

Once installed I got scared when i saw that i have more than 350 tabs open, but i was not really surprised... ;)

It does just one thing (total number of tabs), but it does it smoothly and well.
Simple and effective! well implemented with the FireFox UI without disturbing your eyes.
Strongly recommended to those who need to scroll horizontally to switch between tabs...

Thanks a lot to the developer/Perry
