need help hiding text in JS

<h1><a href=”http://www.mozilla.org“>
[COLOR=firebrick]<script language=”JavaScript” type=”text/javascript”>
<!– hide this from other browsers
if (navigator.appName == “Microsoft Internet Explorer”)
document.writeln(“Download Mozilla… much better.”);
//done hiding
</script>[/COLOR]
</a>
</h1>

so if you check my [URL=http://fadi.omniro.com]site[/URL] with IE you’ll get the msg that you need to get mozilla but if use any other browser then it won’t show and that’s what exactly I want it to do!
However if I use this code up in the beginning of page everything get screwy if I don;t use <p></p> then i lose next image if I use the <p></p> i lose the whole text aaaaaaah can you improve this code for me?

Also in #JavaScript _↴
