I agree. The colors are too bright, green, blue, yellow, red, all very shiny and saturated. Some things changed for the worse, where there was nothing wrong. The close buttons on tabs have a focus style that's difficult to see. The downloads window, I don't know why they changed the visuals on that, there was really nothing wrong with it. And things that needed some work, like the customize toolbar window, still have a terrible interface (why not just show the buttons as I drag them, why can I resize that window until I see nothing?) The good thing is, there will probably be an add-on to change everything back.
