Why does a page on my website turn blue if I scroll beyond halfway?

One page only on my website, one that contains a lot of information, when viewed in Firefox but not in any other browser, looks normal until I scroll past approximately halfway down the page, at which point all the text on the page becomes covered in what appears to be a blue background. The page content is still there but obviously can't be read because the text colours are not compatible with the background.

Firefox version is 21.00 but website users are experiencing this also and I wouldn't know which version they're using.

Website is www.sloanegrammar.co.uk and the page is Sloane History.

Yes, that looks like the bug I mentioned above.
I works fine for me on Linux, but with a Windows version it shows the appearance that you described at about y=32000 according to the DOM Inspector with the background color showing instead of the background image.

Thanks, cor-el. A member who uses Ubuntu also said he views the page perfectly in Firefox.
