“Images with ICC profiles now render properly on all monitors.” via Mozilla Firefox 3.5.2 Release Notes. I just upgraded and color management is working for me now.
Firefox 3.5 has been released and I have been using Firefox 3.5 since it was 3.1 beta. It good, head over to Mozilla.com and get your fresh copy now.
I’m now using Firefox 3.5 beta 4. They bumped up the version from 3.1 beta 3 to 3.5 beta 4. Beta 3 worked really well so I expect beta 4 to be “betterer”.
