How to check who's unfriended you on Facebook

Summary: Have you ever wondered who just unfriended you on Facebook? The social network will never tell you, but this Google Chrome extension will.


Update: How to see who unfriends you on Facebook

If someone accepts a friend request from you, Facebook sends you a notification, both on the service and via e-mail (unless you disable this functionality). If one of your friends deletes (or unfriends) you, Facebook does not notify you. The company says so explicitly in its Facebook Help Center:

If I unfriend someone, will they be notified? No, but all friend links are reciprocal, so you will be removed as a friend from their friend list as well.

Facebook does this so users don't feel guilty when they unfriend someone. Unfortunately, some users just can't help themselves and are unbearably curious who is unfriending them, and when.

That's where the Google Chrome extension Facebook Friend Checker (FFChecker) comes in. You can download it yourself from the Chrome Web Store. Also see the following Photo Gallery: How to check who's unfriended you on Facebook (screenshots).

FFChecker keeps track of your Facebook profile in the background and notifies you on a frequent basis who unfriends you. Here's the official description: "Regularly checks your Facebook friends to check whether anyone has removed you from their friends."

You can set how often the plugin should check your friend list (the default is two hours). The time limit is there so that FFChecker isn't constantly working: it only activates when it's time to check. Two hours is way too frequent; setting it to 24 hours or even more should be enough for you.

When FFChecker detects that one or more of your friends have unfriended you, it displays a message informing you of the event. The message also includes a link to ex-friend's profile page.

The extension works because it can compare the list of Facebook friend ids saved in Chrome's cache. If you clear your cache (Wrench menu => Options => Under the Bonnet => Clear browsing data…), the plugin won't work until Chrome caches you Facebook Friend List again.

This Chrome extension is a modified version of the original Greasemonkey script, which is available on and was developed by the user znerp.

    In case one doesn't use Chrome, or just doesn't want to deal with extensions, then one can use a native Facebook app. I found XTracker to be good at it, nice UI and no ads:
  • RE: How to check who's unfriended you on Facebook

    Frankly, the rise of social media has made it so easy for people to live completely false lives! I know people who don't exist outside of FB. Let me explain: I know several people who speak to no one, add nothing to the verbal conversation when you see them out and about, but man let them get a hold of a mouse or a smart phone and these people have much, much to say, most of it fantasy. I have been "unfriended" by a young mother after she came to pick up her child from the nursery at church and decided that I was "mean" and "judgemental". All this she poured out in a FB message to me. When I suggested we meet for coffee and discuss this because I was mystified and felt bad that she thought this. She promptly unfriended me and does whatever she can to avoid me. I only found out that she had done this because she still comments on things I say and since we know the same people, it said she was a friend of a friend and I thought, that's wierd, I thought she was my friend too. So I checked her friend list, it's easy to do, and I was gone!
