Background images are red on some web sites
Images on some websites are completely red, filling the entire frame for the image. I'm not sure this is a problem with FF, as the same issue shows up in IE, and some of the ads underneath MSN Live Messenger.

You may have security software (firewall) or other Ad-blocking software that is causing it and that changes the image to an 1x1 red GIF image that Firefox expands.
