How bizarre, as soon as I scroll down past the subtitle the entire page goes white and never comes back. Happens whether I drag the scrollbar, use the down key, use the page down key, or swipe on the touchscreen as well. (latest firefox on windows 8 on a thinkpad tablet 2 in case anybody's curious)
