This may be stale and you already know from the first, but I feel the need to post this. if you ever read a post titled Pojok Kanan ataS, it only works on the old version of facebook and now facebook has a new look as you know, and then how to log out?
left click the "Account" button in the upper right corner. Go to the bottom, and select "Logout." Its pretty simple, and can save you plenty of headaches.
