Modern and Sleek Rated 5 out of 5 stars

This theme got a very well design, I am sure the author understand design at all. Very nice arrangement, elaborated in every details, it's very thoughtful that it's not everything goes dark, not like the others, at least I can see the light background color on url bar; Just one thing, maybe the contrast is still need to tune it a little bit brighter.

This review is for a previous version of the add-on (1.0725). 

Thanks for your comment. I am not pretty sure about the contrast stuff, actually I am just trying to add more contrast between the active tab and the others, maybe I will consider to make others look a bit brighter later on.
