Firefox 3.5 tampers with image colors by default
Tonight I was bothered that an image I was looking at in my browser looked washed out and when I loaded it into Irfanview to correct it and study it more closely, somehow it was already darker in Irfanview.
At first I started wondering if I accidentally turned on some kind of automatic option in Irfanview but then I remembered that Firefox 3.0 had image color correction added, but was off by default.
Sure enough Firefox 3.5 has color correction turned ON by default. Even for existing installs that simply upgraded, it apparently turns it back on all by itself.
So go to about:config and find
and set it to 0 (zero)
