This affects the default theme and the two extra themes I've installed (GrApple Yummy and GrApple Delicious from http://www.takebacktheweb.org/) Reproducible: Always Steps to Reproduce: 1. Install FF 3 beta 5 on OS X 2. In about:config, set gfx.color_management.enabled to true 3. Restart the browser Actual Results: As described in details: title bar and button bar background colors are different shades of grey Expected Results: Title bar and button bar should be the same shade of grey (as they are when color management is turned off)

I believe this is a duplicate of bug 403169 which was fixed on 4/07

Apologies Stephen, you're right.
