I am using a GTK theme with some dark elements, which causes problems in some applications. One of them is Firefox: the URLs in the drop-down menu of the address bar are dark blue on a black background, as in the picture:
How can I change this color, or the background color, without changing my GTK theme? I remember that once was possible to do with the userChrome.css file, but I can't find it again.
I am using Firefox 14.0.1 under Linux.
I just wrote a quick Greasemonkey script that checks the computed style of the body element and changes it to black (you probably want to choose a different colour):
(function () {
if (window.getComputedStyle(document.body, null).getPropertyValue("background-color") == "rgb(255, 255, 255)") {
console.log("Setting new background color...");
document.body.setAttribute("style", "background-color: #000000;");
}
})();
The problem with these types of things is that unless websites are designed extremely well, there will be blotches of white on black.
The answer by @DavidPostill for changing "Menu" in "Personalization > Window Color and Appearance", does not apply if you are running the Aero theme. It needs the theme to be set to "Windows Classic". Not even "Windows Basic" will work.
If you want to change the menubar, you will need to hack Windows software using a resource editor or even a debugger. The only Windows software I know that might take part in the display is Shellstyle.dll, and it is not at all sure that it is the one that draws the menu bar.
An example of how such hacks are done can be found in the article :
How to Auto-Hide or Disable Command Bar in Windows Vista and 7 Explorer.
However, you are on your own for discovering where the menubar colors are set.
But even if you do, your changes might render your computer unusable, since essential Windows components are digitally signed by Microsoft and are therefore unmodifiable. Even if you managed to hack Shellstyle.dll, the changes might be undone by the next Windows Update, so you may need to repeat them time and again.
Your real choices are really two : Use the "Windows Classic" theme,
or accept the limitations of the Aero theme.
Anything else is playing Russian Roulette with the health of your computer.

The solution to this without installing add-ons is to modify userChrome.css.
If userChrome.css doesn't already exist in your profile/chrome/ folder (or if the chrome folder doesn't exist either) you have to create it:
Then add something like:
And restart Firefox.
