Can you explain what you want, and please don't use all caps. Firefox has personas that go behind the toolbars and make them hare to read, are you looking for a plain pastel background for toolbars. You're on a Mac so it does not involve Window Aero transparency. Where is this background supposed to be. I color my toolbars so I can identify one profile from another :http://dmcritchie.mvps.org/icons/ff_colorized_profiles.png
