Fullscreen + Embed Issue in Firefox

I am using this code for a fullscreen flash page, which is working fine in IE. I am using the javascript fix so that I don’t have the embed (gray box) issue, but now I am not able to get the fullscreen to work in Firefox. The only suggestions I have found on fixing the issue refer to pre-embed issue fixes and I am not figuring out how to work this in to my current code.

This is what I have:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<script type="text/javascript" language="JavaScript1.2" src="flashobject.js"></script>
<style type="text/css"> 
body { 
height: 100%; 
width: 100%; 
margin: 0; 
<title>CBS: Who We Are</title>

<div id="firstflash">
This text gets replaced by the swf file if the user has Flash installed.
<script type="text/javascript">
 var fo = new FlashObject("http://www.cbservices.org/cbs/test/jill/CBS/CBSwhoweare.swf", "firstflash", "100%", "100%", "8", "#003366");
   fo.addParam("quality", "best");
   fo.addParam("scale", "noscale"); 

These are the threads I have found with advice getting Full Screen in firefox:

Can someone please give me a clue how to work a solution into the code I am using?
