Could be due to a conflict with adblock+... The site is shown without the long list of links, as advertised, but then below the whole site is displayed all over again and the second time around it does have the long list of links. It also removes the third column. Makes things very messy. This is on Firefox 8.0.1

This does, indeed, remove the long list of links and makes the page shorter but the ad code is now visible. This might be a conflict with the watchlists of Adblock Plus.
