Since you're parsing it as XML, you should let the parser know that your 
elements are HTML. This is done by specifying an appropriate (XHTML) namespace.

Also if you go that route, you ought to be calling adoptNode before appending 
the parsed tree to the tab's document, see http://www.w3.org/DOM/faq.html#ownerdoc

And, not selectedTab, but gBrowser.contentDocument.

If you wish to print HTML code, it probably would make more sense to use 
document.open / document.write
