Mozilla Software → [FireFox] How do I get Fx to use Windows 8 chosen color?

Fx on XP Pro, Vista Ultimate, and Win 7 beta (only time I had Win 7) all use my chosen Windows color not just for the Active Title bar but for tabs vertical on the left side and the vertical scroll bar on the right. Fx on Windows 8 uses my chosen Windows color for the Active Title bar but uses an ugly pale gray for the tabs and hard to see pale gray for the right side scroll bar. Opera 12 uses my chosen Windows color for the tabs vertical on the left but it also uses the difficult to see pale gray vertical scroll bar on the right. I use Tree Style Tabs in Fx but I have always used that on other OSes also and I have my Windows color used on other OSes so Tree Style Tabs is not the reason for the pale gray background of the tabs inFx in Windows 8. The pale gray is particularly bad on Fx because the left side vertical scroll bar (put there by Tree Style Tabs) is very narrow and very difficult to see. If it was green that would be much better.

Is there a way to get Fx to use my Windows color for the tabs? Since Opera uses the color there should be a way to get Fx to do it. To get Opera to do it, I just set Opera to the default Standard theme which automatically uses Windows settings. Since all the browsers use that horrible to read, and depressing, light gray color for the right side vertical scroll bar in Windows 8 maybe that cannot be changed (except maybe with Classic Shell but I decided to try Start8 and I like it so I don't think I want to use Classic Shell to get the right side scroll bar a decent, readable color --it should be my custom Windows chosen color without needing a third party application, but if not possible in Win 8 at least the left side tabs in my Windows color is possible because Opera does it).
