Oh my god, when will Firefox shut up about its motherfucking colours!? Themes have been a feature since forever, none of this is new. Also, I DO NOT want my fucking userchrome to be colourful, and I DO NOT want to be constantly bugged about this. It's a fucking browser. I want iit have a reasonably high contrast and otherwise blend into the edge of the screen, because for a web browser, the UI is not important and should not stick out.

I respect if someone has different opinions about UI, but it pisses me off to no end that Mozilla doesn't respect mine.
