Custom Module help.., Not displaying anything in Firefox. Options

[protegechris]

I'm using this code:

CODE

<!-- begin code provided by createblog.com -->
<script>
titleContent = 'Affiliations';
moduleContent = ' stuff here ';
sub = subTitle.parentNode.parentNode.parentNode.parentNode.parentNode
sub.insertAdjacentHTML('beforeBegin','<table border="1" cellspacing="0" cellpadding="4" width="100%" class="left"><tr><th valign="top" align="left" class="left">' + titleContent + '</th></tr><tr><td valign="top" class="left">' + moduleContent)
sub.insertAdjacentHTML('beforeBegin','<BR>');
</script>

<!-- end code provided by createblog.com -->

However, the modules are not displayed in Firefox, what's the cause of this?

[kill me please]

if you use this custom module script it works in firefox i think.

<!-- begin code provided by createblog.com --><br /><div id="customLeft" style="display:none"><br /><!-- module:start --><br /><table class="left" cellSpacing="0" cellPadding="4" width="100%" border="1"><br /> <tr><th class="left" vAlign="top" align="left"><br /> [-MODULE-]<br /> </th></tr><br /> <br /> <tr><td class="left" vAlign="top"><br />STUFF HERE<br /> </td></tr><br /></table><br /><br/><br /><!-- module:end --><br /></div><br /><script><br />var sbpc = document.getElementById('customLeft');<br />var myForm = document.getElementById('__aspnetForm');<br />var leftSide = sbpc.cloneNode(true);<br />leftSide.style.display = "block";<br />if(!document.all){<br />range = document.createRange();<br />range.selectNode(myForm);<br />range.insertNode(leftSide);}<br />else{myForm.insertAdjacentElement('afterEnd', leftSide);}<br /></script><br /><!-- end code provided by createblog.com -->
