Find Out When Someone De-Friends You on Facebook

Want to be able to know which of your ‘friends‘ has de-friended you on Facebook?

“Yes” I hear you say?

This guide will show you how.

Facebook Friends Checker is a Greasemonkey script that regularly checks your Facebook friends to check whether anyone has removed you from their friends.

When the script detects that someone you used to be friends with is no longer one of your friends, a message will appear informing you about who it was and giving a link to their profile page.

Setup

Firstly, this only works with the Firefox browser. If you don’t already have it, download and install it now.

Next you need to install the Greasemonkey add-on for Firefox.

Greasemonkey is a Firefox extension that allows you to customize the way webpages look and function. Greasemonkey allows you to insert Javascript into the local display of web pages in your browser. Nothing changes for anyone else, but images, links or text can be added or hidden automatically when you visit a web page that a script has been written for.

Go to the Greasemonkey add-on and click <Add to Firefox>,

Click on <Install Now>,

Then restart your browser,

You have just installed the Greasemonkey add-on for Firefox.

Now head over to Facebook Friends Checker.. and click on <Install>,

When the Greasemonkey Installation pop-up appears, click on <Install>,

Done! You have now just installed the Facebook Friend Checker script!

Time Interval for Checking

By default Facebook Friend Checker checks your Facebook friends list once every 2 hours. To change this time.. login to your Facebook account.

Now that you are logged into Facebook, click on Tools in your browser –> click on Greasemonkey –> click on User Script Commands –> click on Set time interval to check for removed friends…,

Change the time interval as required,

Here is a brief explanation of how the Script works.

Any time a page is loaded on Facebook, the script will run and it will follow the following basic algorithm;

• If the script has checked your friends in the past <<insert number here>> hours, do nothing.
• Otherwise, load a page on Facebook with a list of all of your friends.
• Go through each of these friends and add them to a list.
• Compare this list with the list saved the last time the script checked your friends.
• If someone was on the list before who isn’t now, post the box informing the user.
• Save the new list of friends over the old one.
• Save the current time as the last checked time.

De-Friended!

I have tested this out by getting my wife to remove me from her friends list,

Then confirming this by clicking on <Remove>,

Done! I have just been removed from my wife’s friends list.

Facebook Friend’s Checker

When I log back into my account I am notified that someone is no longer my friend.

Click on View Profile to see who has removed you from their friend’s list,

.. and lo-and-behold.. my wife’s profile appears letting me know that I have been removed from her friend’s list (and that is my beautiful daughter not my beautiful wife!),

So there you have it.. you can now be notified of who has removed you from their friend’s list in Facebook.

If you have any issues or questions with the Facebook Friends Checker script, please post your questions on the forum here.

Enjoy!
