If I go to any page, lets say the main forum index, and then search for something within the page using ctrl-f in firefox, the text it finds isn't actually on the page, but it's just beneath the page. As an example, go to the main forum page and ctrl-f for luxury hotels. For me, I always have to scroll down to see the text that firefox found. On any other site, the located text is always visible in the page. If I close the chatroom bar then I do see the located text.
