Facebook Error! Help! Can't Exit Facebook Account! Urgent!?

[Joao]

I really need help quick on an issue I have encountered on facebook. Today I was using facebook in the afternoon without a problem. When I logged back on facebook tonight, I encountered a serious and really irritating error, glitch, bug, or even virus. Whenever I try to log off my account on facebook by pressing the "exit" button (where I have always logged off from), I'm redirected to my news feed instead of exiting my account. This is really annoying, since there are other people who use this computer to go on facebook once in a while. I don't understand why did this just happened from night to day, I did not download anything today, so I don't think it's a virus (if it is I wonder why did it only trigger tonight, since I must have gotten it earlier). I don't understand why was facebook working fine during the day but not anymore now. I really need help on this please. There are other people who use this computer, and I can't seem exit my facebook account in any way. I tried pressing the exit button tons of times, but I just go to my news feed every single time. Please help me, this is really important!
Oh and BTW, by "exiting" I mean log off my account. And I am sure I am logging off in the right place, since that's the way I've always logged off, and it has always worked until now.

try closing the browser, and rebooting, then go back to Facebook and check, if its still logged in, try logging out then, it should work.
