How to sign out of all active Facebook sessions from a single device

It’s easy to forget to sign out of Facebook every time you move on to doing something else.
For example, perhaps you’re driving home from a party and you suddenly realize that you forgot to log out of Facebook after borrowing the host’s PC.
It’s extremely important that you always log out of a Facebook session if there’s a possibility of someone else using that computer or mobile device after you’re finished using it.
As luck would have it, it’s very easy to log out of all active Facebook sessions from any device that you happen to have at your disposal by following the instructions below.
