Results after the first one fail to load in the latest Firefox. It looks like a Firefox bug btw, the style and script tags are not being added to the created iframes (except the first, which is always ok) unless I mess with the timing, either by using a 100ms delay in setTimeout() or a breakpoint with Firebug. PS: it's a fantastic tutorial, thanks for writing it!
