Firefox is suffering bug #1026579 which makes it lock up (freeze). The freezes are intermittent, the pause between them during which Firefox is responsive again last about 1 second, so I have a long series of intermittent freezes during the space of several minutes. During this Firefox grays out and get back its colors according to the frequency of the freezes.
The problem is that after it stops freezing, it become black and white (grayscale), the application doesn't get back its color (including the Gnome minimize-maximize-close buttons, etc). It's a different gray from the black when the app freezes, more like applying a grayscale filter on it.
Screenshot attached, with Google Chrome for comparison.
PS : if I open a new window, this one is not gray.

Workaround (which should work):
1. Install package: compizconfig-
2. Run: ccsm
3. Fading Windows > Dim Unresponsive Windows = OFF
