What does it mean when I log into Facebook and a pop-up comes out saying "[JavaScript Application] Error: jQuery("#fb_menu_account a", document).attr("href") is undefined"? I would like to know what I can do to fix this. The site ends-up running slow. I have tried clearing the cookies and cache, but that doesn't work.

URL of affected sites

http://www.facebook.com
