If you’re a Facebook user with a few hundred friends, it’s extremely difficult to keep track of all of them. And sometimes, you’ll be unfriended – it’s just a sad fact of life. Whether you piss someone off or simply become irrelevant to their social sphere, theres a good chance that any Facebook user will lose multiple friends every year.

Of course, Facebook doesn’t offer an inline method to let users see when they are unfriended. But now, you can not only see a list of everyone who has unfriended you, but you can get notifications right when it happens with a new script called Unfriend Finder.

And it’s totally legit. It’s not one of those scams that have been going around for a couple of years that end up just spamming the hell out of your friends.

The script was created by Edouard Gatouillat and works with Internet Explorer, Firefox, Chrome, Opera and Safari. It’ll simply install automatically on Chrome, but Firefox users will have to add-on Greasemonkey before installing it.

When the jerk unfreinds you, you’ll get a notification within the new “Unfriends” box appearing on the top right of your Facebook page. You’ll also get a notification to the actual Facebook notification tray:

Once you click on “unfriends,” you’ll see a list of everyone who has unfriended you:

The script allows you to see who has deactivated their profiles, lets you manage your sent pending friend requests and it also shows you who has rejected your friend requests. It’s important to note that it’s not retroactive, meaning you won’t be able to see who unfriended you before you installed the script.

This script allows users to do something they’ve wanted to do for a long time. Vindictiveness just received some major help.
