Div background image doesn't work in Firefox

But it does work in IE.  This is a widely known issue, and I've tried many solutions suggested, and nothing is working.  Maybe someone can take a look and see what I'm missing or doing wrong:
 
<div id="Banner" style="background: rgb(65, 74, 111) url(/public/Banners/banner11.jpg) no-repeat scroll 100% 0pt; -moz-background-clip: -moz-initial; -moz-background-origin: -moz-initial; -moz-background-inline-policy: -moz-initial;">
<ul>
<li>
<a href="Default.aspx">Home</a>
</li>
<li>
