How do you make the address toolbar colour follow the Windows theme colour?

Question

Firefox used to follow the Windows 7 theme in the address toolbar; if the windows are coloured green then the address toolbar is coloured green. Now the Address toolbar is a gross grey-blue colour. Previously, only the tabs and the bookmarks toolbar had their own yucky grey-blue colour, but it's spread upward!
How do I change this?
I would really love any solutions that did not require me to install a new theme, as whenever I have done that in the past it has always impaired performance (slows down the loading of the browser).

You can use a custom style rule to change the color. Custom style rules can be applied to the user interface either using the Stylish extension or by creating a file named userChrome.css in your profile (settings) folder.
To create the rule, though, I think someone might need to see the particular shade of green. I don't know whether it is possible to detect that automatically.
Alternately, you could make the background of the address bar transparent so the color behind it shows through. There's an example of that kind of rule in this thread: [https://support.mozilla.org/questions/1000123]. If that looks too naked, one might try a translucent background (e.g., white, but only 10% opaque so most of the background color shows through).
