FireFox 3.6.12 doesn't display an iFrame (an Amazon sales link) that displays in IE8, Chrome, and Safari. It displays iFrames of PDFs on the web site.
I support www.oaklandsymphonychorus.org, a site using DotNetNuke 4.9.5. I added an iFrame module to the site using the URL in this code:
<iframe src="http://rcm.amazon.com/e/cm?t=oaklsympchor-20&o=1&p=8&l=as1&asins=B002FQJT3Q&fc1=000000&IS2=1<1=_blank&m=amazon&lc1=0000FF&bc1=000000&bg1=FFFFFF&f=ifr" style="width:120px;height:240px;" scrolling="no" marginwidth="0" marginheight="0" frameborder="0"></iframe>
The iFrame displays in IE8, Chrome, and Safari, but not FireFox.

Solution: Add id and name attributes to the iframe-tag.
