How do you logout of facebook on a cruz tablet?

[suzyqnelly]

Ive searched this on the internet and can't find anything. i see no logout button. or no settings or applications buttons. i am borrowing someone else tablet. when i close out the browser and reopen it still has me signed into facebook.
The only buttons i see at the blue bar at the top are 1 with 3 horizontal lines and the other one says Sort on it.
