Today I learned that Firefox has a bug that has been outstanding for 9 years that affects the way it displays images. When you use Firefox on a second monitor that has a different color profile it uses the profile from the primary monitor. If your displays are significantly different, then your colors will be dramatically different. In my case I’m using a MacBook Pro with an older NEC display as a second monitor, the color gamut is quite different, so when I have Firefox on the second display the colors are horribly over-saturated, move it back to the primary monitor and all is well.
Just thought you all should know so you’re viewing images on NPN properly, I’ve probably given some bad feedback on images because of this bug, argh! The solution is to only use Firefox on your primary monitor, or use Chrome or Safari, which do not have the bug.
