How to fix color management problems in Mozilla Firefox

Recently I've been looking at a Firefox color management problem. Certain colors on websites seemed to be off, especially white backgrounds that looked like they had a yellowish tinge. The issue was encountered on Mozilla Firefox 11.0 but I've actually been having this issue for quite some time already.

This problem seems to affect only a small proportion of Firefox installations out there. Among my machines, which include 2 desktops, 3 laptops and another from the office, only one of the machines seems to have been affected. Apparently the issue had been there since Firefox 3.5 where color management was enabled by default, but I did not notice the colors were off until some time after the graphics drivers were updated. It could be due to that, but I couldn't be precisely sure that it was the cause.

I've managed to fix the problem by changing the color management setting to disabled. Here's how to do that :

  1. In the Firefox address bar, enter "about:config" (without the quotes), as in the screenshot above.
  2. There's a warning about "This might void your warranty!". Having paid exactly zero dollars for your software, there actually isn't any in the first place, so click on the "I'll be careful, I promise!" button.
  3. Now do a search for the color management setting. Simply type "gfx.color" to start searching for the property name.
  4. Double click to change the setting from 2 to 0.

That's it.

Color management will be disabled and the colors should hopefully look normal now.
