I noticed while browsing flickr that my photos along with other peoples photos are extremely dark, in the previous version this was not the case nor with IE8, Chrome, Safari, etc. Anyone else with this problem?

http://www.flickr.com/photos/ogden2k/3528350349/ as an example.

looks fine on mine. I am using same build of firefox as yours.

maybe some kind of color profile problem?

toggle the color management preference in about:config, i think you need to try 1.

On both Beta 4 and beta99 it is set to 2, which is the way I want it to be, as other Fx users will default to that as well. I'm concerned with the darkness of the images. I'll look into the color profile for the computer I'm on now to see what it's set to.

Hmm, very strange. I reinstalled my video drivers and the issue is resolved. Disregard.
