What if there is no Account button to log off Facebook? What do I do now?

UPDATE: Actually we all still have the triangle/arrow up there so you must have a problem in visualizing it. What's on the right of your "Home" button then?
Maybe you should try zooming in or out the page or open it with a different browser

You said you've already asked this and didn't work, but the only thing I can do is try to drive you step by step.

At the right up corner you should have: 1. your profile picture with your name on its side. 2. the "Find friends" option. 3. the "Home" option. 4. a small white triangle pointing down.

Click on the triangle and a scroll down menu will appear. There you have again several options: 1. Advertise on Facebook. 2. Account Settings. 3. Privacy Settings. 4. Log out. 5. Help.

Simply click on log out
