No Drop Down Menu On Facebook?

I have a major problem in facebook.The problem is that i don't get any drop down menu.I wanted to edit my profile to add a language but there was no drop down menu.I have added languages before and i know that when you type in the text box a drop down menu appears for you to chose a language from.I am not getting that menu.Also when i try to find people on facebook,i want to add a location filter but again there is no drop down menu.Usually lets say i type "cali" as the location i would get a drop down menu with various names such as "Los Angeles,California" etc. to chose from.I am not getting that.I have tried opening facebook in chrome,internet explorer and mozilla firefox but in vain.Even restarting my computer does help.I didn't even change any privacy or account setting.Please help me!
