Rated 5 out of 5 stars

As far as dark, red-highlighted themes with animated icons, this one has NO competition. Nearly every visual element of the FF layout has been changed, yet the icons and graphic elements show no conflicts such as misalignment with standard design elements and fonts as you see with many other themes that try to change this much of the UI. I didn't have to make any color or font adjustments whatsoever, and it works perfectly with every addon that correctly adapts to themes. The animated icons add life to an otherwise blasé browsing session. I wouldn't mind seeing some of these design elements in the Photoshop ui or Windows.
I would donate to this effort, but some of the other theme developers should stop begging for undeserved reward and take heed of this theme's wonderworks. I can tell it was a product of pure devotion.

This review is for a previous version of the add-on (1.0).
