User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0b8pre) Gecko/20101124 Firefox/4.0b8pre Build Identifier: The current background ( http://tinyurl.com/2upbong ) is quiet different than the screenshot ( https://bugzilla.mozilla.org/attachment.cgi?id=491016 ) of Bug 601022. Current is just single colors, the screenshot has some decorations (oblique strips) on it. Reproducible: Always
I think I've figured out why this is happening. The background-color property is set to -moz-dialog. By changing this to #CCD9EA (as in the image below), everything seems to be fixed. http://people.mozilla.com/~jboriss/bugs/addons_manager_styling/windows_7_background_color_and_graphics.png
There's a typo in extensions.css...
