Header/Nav bar alignment problem in Firefox (Mac)

[Guest funsizealex]

I am trying to align an overlapping nav bar/background image div with a header div that has a bottom border.This is my code:

.header{width:100%;height:85px;border-bottom: 1px solid #000;}.nav{ width: 100%;height: 110px;background-image: url(../images/wburg.jpg); background-repeat: no-repeat; background-position: 30px 15px;z-index: 1000;}.nav ul {float:right;width:100%;margin-left:195px;margin-top: 60px;list-style-type: none;}.nav a {float:left;width:6em;text-decoration:none;color:#000;padding:0.2em 0.6em;font-size: 12px;}.nav li {display:inline;}

and then the html is this:

<div class="header">	    	<div class="nav">                </div></div>

Right now it is appearing as I want it to in the following browsers/platforms:IE (Windows)Safari (Mac)but not in Firefox (Mac).Site address: http://www.alexandraorgera.com/portfolioI would appreciate any advice or help you can give me, as I am completely new to css. This is my first attempt at designing a site with it. Thank you!

The page looks identical in Safari and Firefox 1.03 Mac. Also in Opera 9.01 Mac.I checked all the links in the top menu and some of their left-hand links, but not all. Safari and FF behave the same. Am I missing something?PS—if you have a minute and if you have IE6, could you have a look at my request for a page check, a few posts above this.
