I'm liking it. I am color impaired, what most people call "color blind", though the term is wrong. With almost all themes, I have trouble finding the active tab at the top of the window. I've tried a lot of themes, both dark and light - this one works. Not only can I find the active tab, but I can READ the titles of the tabs. Most themes for color deficient people are so butt ugly, and also fail to solve the problem. TheWolfBunny64 got it right with his theme! Thank you! I'm installing on all of my Firefox derivatives. (For others who are searching, Jungle Gem theme works great on Chrome based browsers.)
