After footer-extension, how can I get the main content to be shown entirely?

While this works fine in Safari, all other browsers do not show the whole site - they cult the thumbnails (show just half of it) - so I would love, if someone could tell me, how I can force all browsers to scroll deeper (same problem on other parts of the website - so a "site-wide" solution would be appreciated)
