How to Find out When Someone Unfriended You on Facebook

When you notice your number of Facebook friends is decreasing, finding out who deleted you as a friend isn't easy. Through Facebook, the only way is to inventory your friends to determine who is missing -- if you have hundreds of Facebook friends, as many people do, it's extremely difficult to find who is missing. Grease Monkey has a free add-on that can help, although it only works in the Firefox, Google Chrome, Safari and Opera Web browsers.
