Want to find out if and when someone has deleted from the list of friends on Facebook? Find out, in theory, is not a thing possible, since Facebook does not make available to this information. But, in reality, thanks to Unfriend Finder, a plugin that you can download for free , that will be possible.
This simple script can be installed on all major browsers (Firefox, Chrome, Safari, Opera and Internet Explorer in addition to derivatives RockMelt, Flock and Fluid) with one click.
Unfriend Finder will notify you when you delete a friend from the list or off their profile. The application also allows you to keep track of your friend requests.
Unfriend Finder was created by Edouard Gatouillat and installs automatically with Chrome, and Firefox users must first install the Greasemonkey add-on.
Once installed, you will see two new features on Facebook: a new Unfriends tab at the top left of the screen and a ‘Unfriends option in the Favorites list. When you exclude someone from the list of friends, a notification will appear in red on its tab.
Obviously, the script will not say which friends you have previously deleted, but only those who cancel after installing the script itself.
