Simple, but Very Effective Rated 5 out of 5 stars

This add-on deserves 6 stars. I really like being able to keep Firefox’s interface dynamic without the bother of cumbersome themes and personas. The combination of styles and colors [which can be tweaked using hue, saturation, opacity and brightness controls] allow for an infinite number of affectations.

I have an idea for the wishlist: I would really like the option of being able to save the configurations I create. It would be great to be able to select from a list of former configurations. Thanks much for this extension!

This review is for a previous version of the add-on (2.1.1).
