http://www.googleadservices.com/pagead/conversion.js throwing an exception

[annibigi]

I have included ga script in my site and the line

 

<script language="JavaScript" type="text/javascript" src="http://www.googleadservices.com/pagead/conversion.js">
</script>

 

throws an exception like

 

uncaught exception: [Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIDOMHistory.length]" nsresult: "0x80004005 (NS_ERROR_FAILURE)" location: "JS frame :: https://www.googleadservices.com/pagead/conversion.js :: j :: line 3" data: no]

 

 

I am using Mozilla Firefox and i have firebug installed.So i could view this error.

 

What could be the problem?
