Bacground color on navigation links

[ZeroShade]

I have put an outset border around my navigation links. And a background color as well... but, in Firefox the part where the bullets (which I have selected to "none") takes that color as well and interferes with my background. I tried setting the z-index but it doesn't help because the image overtop of the selection keeps the links from being clicked. How can I add background color to my links without the bullets (that arn't there) being colored as well?Oh, I got it, i put the background color in the list instead of the unorderlist.
