Fixing Funny Image Colors in Firefox on OpenSUSE 11.3

Actually I don’t know if this affects other Linux systems or even other operating systems, apparently it has something to do with the way newer Firefoxes handle colors. Anyway, what happens is that Firefox renders some images properly, but renders some others with incorrect colors. This behaviour can be fixed by changing some of Firefox’s config values. Instructions as follows:

1. Get into the config interface by opening a tab in Firefox and keying in “about:config” into the address bar. Read the warning and continue.
2. Look for gfx.color_management.mode and set its value to 0, and then look for gfx.color_management.rendering_intent and set its value to -1.
3. Restart Firefox
