I'm using the Siberia theme on my site: http://helpinchrist.org. I've changed the logo around, so its the whole big blue banner. The theme works fine on IE7 with the navigation menu showing up from the very left, but in Firefox, the navigation menu starts to list the links right after the logo. What can I modify to make the nav menu appear from the very left like in IE7?

heres the code:

grey.css

body {
  color: #292929;		/* font color */
  background-color: #59a9c0;

div#masthead {

}

div#header .header-right {
	background: url(../images/container_tr.png) 100% 0 no-repeat;

}

div#header .header-left {
	background: url(../images/mast-l.gif) 0 0 no-repeat;
}

div#footer-wrapper {
