It's happened in the past. I went to a site with Firefox and the page went blank while it was loading, then it stopped loading after a while. Problem still exists if Ad Block Plus is disabled. No problem loading the page in Safari.

Try here. The bottom of Firefox, the load message at the bottom left, briefly says doubleclick.net while the page is loading. I've had the same problem with other sites that say doubleclick.net.
