Hi all, I just upgraded to 4.4.1.and upgraded all modules to the latest versions and now have a problem with displaying Google ads in Firefox. They work fine in IE. The site is www.panama-zone.com

The script is in an Text/HTML module and is as follows

<SCRIPT type=text/javascript><!--
google_ad_client = "pub-1569107426781548";
google_ad_width = 160;
google_ad_height = 600;
google_ad_format = "160x600_as";
google_ad_type = "text_image";
google_ad_channel ="";
google_color_border = "336699";
google_color_bg = "FFFFFF";
google_color_link = "0000FF";
google_color_url = "336699";
google_color_text = "333333";
//--></SCRIPT>

<SCRIPT src="http://pagead2.googlesyndication.com/pagead/show_ads.js" type=text/javascript>
</SCRIPT>

Any ideas why this won't display in Firefox?
