OK, I apologize ahead of time if I do not word this properly, I am new to themes.

I have the Vista Builder (Win7 Style Builder v. and other such programs that all your tutorials recommend getting. I am looking to try and fix this but I really don't know what things are called specifically. The problem I am facing is that the drop down windows from any link such as: File, Edit, View, History, spell check etc... show up as black font on a very dark background. It's not readable until I mouse-over them.

This only happens with Firefox. Also with IE the address bar is showing up dark gray with black font but in Firefox's address bar it does not.

I am using Windows 7 x64 and the theme is the amazing Blue Moon and I really don't want to get rid of it.

Are there any suggestions that may help me?
