I love this design. If you could make one that had a lighter look to it in the address bar, the active tab was a different color instead of the outline, and you had a light theme for the page instead of dark, it would be absolutely perfect for me. Nice job, really beats most of the others with the fox logo. The placement is good too because it doesn't interfere with the private tab icon or anything.

Hola tarda mucho por intalar

This theme is neat but I have two feedbacks that I think would make it perfect: the image is a bit blurry on a Retina screen and the preferences page is not updated with the new color from the userChrome.css.
