Simple & Clean Rated 5 out of 5 stars

I've enjoyed this theme as it's very straightforward and colorful. If you are having the issue with your minimize/restore/close buttons are completely black, the fix posted by the developers does work.. once you know how the heck you get to about:config. For those of you that don't, you can find it under options --> advanced --> general tab --> Config Editor. You will get a warning message which is meant to keep people from accidentally breaking the software, click the "I'll be careful, I promise!" button and you'll finally be at about:config page. Just find the listed setting and toggle it to off.

This review is for a previous version of the add-on (3.5.5).
