I was looking for an "Everything is Red" Theme. It's difficult to find these types of Themes, that are also fully functional. When I say fully functional, I mean that all elements of a Firefox Window are of the specified color and are fully distinguishable from one another. The Active Tab is way more visible than other Themes I've tested, but it could be just a bit more. The one thing that doesn't quite work is when you're typing in the Address Bar, when the Drop-Down Menu of Suggestions appears, you can't see what you've selected because the Blue Text disappears in the Blue Background. Other than this, I consider this Theme to be one of the best of this Type.
