Problem with the links on Facebook.com?

If you know facebook, across the top there is a menu with options and little triangles with drop down menus. The links work but when I click on the drop down menus, nothing happens and at the bottom of my browser (left hand side) it says %26quot;Error on Page%26quot;. I've never had this problem before and I haven't changed anything on my computer. There are a million departments at facebook and I don't know who I would contact and I'm not sure how to change firewall settings?!! Please help!! THANKS~!Problem with the links on Facebook.com?Have you tried refreshing or logging out and then in. Today, when i went on facebook, it works fine for me. So it is probably just a glitch
