What is your computer system and Firefox?

Are you using an add-on to change the color?

Start Firefox in Safe Mode {web Link} by holding down the <Shift>
(Mac=Options)
key, and then starting Firefox. Is the problem still there?

You can try to edit the prefs.js file in the Firefox profile folder and remove the related lines or rename the prefs.js file to reset all prefs.

Look for:

  • browser.display.background_color
  • browser.display.foreground_color

You can find the profile folder in this hidden location:

In Mac OS X v10.7 and later, the ~/Library folder is a hidden folder.
