Rated 5 out of 5 stars

Great addon. Just installed and tweaked to my liking! I find it very useful indeed, lets you know what tabs belong to what site, by color grouping, set the opacity so you have your active tab highlighted. Not only that but it looks damn cool aswell ;o)

Keep up the great work guys.

This review is for a previous version of the add-on (1.3.5).
