I've been googling around some time now, to find a solution/explanation to this weird "bug".
As seen in the screenshot I've provided, the .png images in Firefox are too pale compared to the same images viewed through Google Chrome. (The background color is black, and the .png images mentioned is the header and the footer, which both are supposed to be black to grey gradients!)
I'm running Fedora 12, and while running Fedora 11, Firefox was showing .png images correctly.
BTW, when running Ubuntu 9.10, Firefox are showing the .png images correctly, which make me wonder if this is some sort of Firefox/Fedora 12 issue!?
Have anybody else experienced this (in lack of a better word) "bug", and is there some solution to fix this.
