Combined this with OLED screen and you have the most good-looking firefox theme ever

Please add a lighter outline (maybe 1px #808080 or brighter) on active tab, because I don't have AMOLED, and I can barely see the grey outline. That's the only reason I'm not using this dope theme. I'm using Black by XI at the moment because I like that strong contrast.

good！！！！！

The best ever
