Can be caused by an error in the page source (backslash instead of forward slash):

<script type="text/javascript" src="js\swfobject.js"></script>

You can contact the site to inform them about that error and ask them to test the site in Firefox.

This site can be viewed using IE and Chrome, just not with FF. Why would it be a code error on the part of the website if other browsers can view it? I'm not trying to be difficult, just trying to understand.

Thank you,

Ok... I don't understand why... but you are correct. They changed the code to

<script type="text/javascript" src="js/swfobject.js"></script>

and it worked... Thank you,
