Want to know who has unfriended you on Facebook?

“Who Deleted Me,” is an app that shows you who has unfriended or deactivated their Facebook accounts. This little widget is also added as a browser extension for Google Chrome, Firefox.

Who Deleted Me shows you who unfriends you. It’s a free extension for your browser that keeps track of your friends.

How It Works?

1. Your friend list is saved the first time you use Who Deleted Me.
2. When you come back on FB, your current friend list is compared to the saved version.
3. That means you get to know “who deleted you”

There is a also a similar app, Who Unfollowed Me, which tracks who unfollows you on Twitter.
