Facebook do notify you when someone accept your friend request and get added in your friend list through notification but they never send notification when friends unfriend you on Facebook. This happens because of the two reasons either the person has deleted their Facebook account (Deleting facebook account cause facebook automatically unfriend that person from the list) or the person has unfriend you purposely/mistakenly.
There are many apps available on web to check, like twentyfeet.com or who.deleted.me but I’ll talk about a simple script that works with every browser, like Firefox, Google Chrome, Opera, Safari and Internet Explorer. Using this script you can keep track of when friends unfriend you on facebook as well as your friend requests.
Unfriend Finder for Facebook
Without being worried you can install this script on your browser. I have tested it on mine and it works perfectly. Here I tell you how it works.
Step 1) Go to the Unfriend Finder and install the script for your browser. It will automatically get install if you are on Chrome but if you are using Firefox, you will have to install Greasemonkey add-on first.
Step 2) Now when it is added on your browser it will add two new features – “Unfriend” inside your facebook account, one at the top right corner of facebook and one on left side under favorites list.
Step 3) Now when someone unfriend you, you will get notify through notification also Unfriend Feature will blink exactly like notification.
Step 5) When you click on Unfriend Feature comes under favorites left side it will come up with 3 options “Pending Requests”, “Settings”, and “Messages”.
Step 6) Clicking on unfriend shows you the list of people – who have deactivated their profile, who have unfriend you, and you’re pending requests.
