Facebook doesn't tell you when someone unfriends you, but you can check manually or use a browser extension
Facebook keeps unfriending quiet — the person who does it won't notify you, and Facebook won't send you a message. You'll only notice if you try to visit their profile and can't, or if you realize their posts stopped appearing in your feed. If you want to know for certain who unfriended you, you have three options: check your friends list against a saved copy, look at your mutual friends with someone you suspect, or install a browser extension that tracks changes to your friends list over time.
The manual method works but takes time. The browser extension method is faster if you check regularly, but it requires you to install software and keep it running. Neither method will tell you why someone unfriended you — that information isn't available anywhere.
Key Takeaways
- Facebook does not notify you when someone unfriends you, so you have to notice the change yourself or check manually.
- The simplest method is to visit someone's profile directly — if you can't see their friends list or recent posts, they may have unfriended you or blocked you.
- Browser extensions like Unfriend Notify or Friend Check can track your friends list automatically and alert you to changes, but they require installation and ongoing access to your account.
- You can also compare your current friends list to an old screenshot or list you saved, though this only works if you saved one before the unfriending happened.
- Unfriending is different from blocking — an unfriend means they removed you from their friends list, while a block prevents you from seeing their profile at all.
Check someone's profile directly
The fastest way to check if one specific person unfriended you is to visit their profile. On Facebook's website or app, search for their name or go to their profile if you have a link to it. Look at what you can see: if their friends list is hidden, if you can't see their recent posts, or if the "Add Friend" button appears where a "Message" button used to be, they have either unfriended you or blocked you.
If you can still see their posts and their friends list is public, they haven't unfriended you. If the "Add Friend" button is there but their profile is otherwise visible, they unfriended you. If you can't see their profile at all or get a message saying the account doesn't exist, they blocked you.
This method only works if you remember who you want to check. It doesn't help you find out who unfriended you if you don't already suspect someone.
Compare your friends list to a saved copy
If you saved a screenshot or list of your friends at some point in the past, you can compare it to your current friends list and spot who's missing. Go to your profile, click or tap "Friends," and scroll through the full list. Check it against your old list — anyone who was there before but isn't now has unfriended you.
This method only works if you actually saved a list or screenshot before. It's also time-consuming if you have hundreds of friends. But it's reliable and doesn't require installing anything.
To make this easier in the future, take a screenshot of your friends list every few months. You can also use Facebook's "read Your Information" tool to export a copy of your friends list, though the export doesn't include timestamps, so you won't know exactly when someone unfriended you.
Use a browser extension to track unfriends automatically
Browser extensions like Unfriend Notify, Friend Check, or Who Deleted Me monitor your friends list and alert you when someone unfriends you. You install the extension in Chrome, Firefox, or Edge, let it scan your current friends list as a baseline, and then it checks periodically for changes. When someone unfriends you, the extension notifies you and usually shows you their name.
These extensions work in the background, so you don't have to do anything after installation. The downside is that they require you to grant them access to your Facebook account, and you have to keep the extension installed and your browser running for it to work. Some extensions are free with limited features; others charge a small fee for full access.
Before installing any extension, check the reviews and permissions it's asking for. Stick to extensions from the official Chrome Web Store, Firefox Add-ons, or Edge Add-ons pages — don't read extensions from random websites. Read what data the extension collects and whether it stores your friends list on its own servers.
Understand the difference between unfriending and blocking
Unfriending and blocking are not the same thing. When someone unfriends you, they remove you from their friends list, but you can still see their public profile and posts if their privacy settings allow it. When someone blocks you, you can't see their profile, send them messages, or find them in search — it's a complete cutoff.
If you try to visit someone's profile and see a message like "User Not Found" or "This content isn't available," they have blocked you. If you can see their profile but the "Add Friend" button is there, they unfriended you. If you can message them and see their posts, they haven't done either.
Being blocked is more intentional and final than being unfriended. Unfriending is often casual — people unfriend accounts they no longer follow or don't interact with. Blocking usually means the person doesn't want any contact with you.
Why Facebook doesn't notify you of unfriends
Facebook keeps unfriending silent by design. The company could notify you every time someone unfriended you, but it doesn't, because that would create awkward social situations and might discourage people from unfriending when they want to. Unfriending is meant to be a quiet action — a way to clean up your feed without drama.
This is different from other social platforms. Twitter notifies you if someone unfollows you (though you have to check your followers list to see it). Instagram doesn't notify you either. The silence around unfriending is intentional.
What to do if you notice you've been unfriended
If you discover someone unfriended you, you don't have to do anything. Unfriending is a normal part of how people manage their social media. You can't see who unfriended you unless you check manually, and the person who did it won't know that you found out — Facebook doesn't tell them you looked at their profile.
If you want to refriend someone, you can send them a friend request again. They'll see it as a new request, not a re-request. If they decline or ignore it, you'll know they don't want to be connected. If you think the unfriending was a mistake, you can message them and ask, but there's no way to know for sure why they did it.
Some people unfriend accounts they no longer interact with, some unfriend because of a disagreement, and some unfriend to reduce their friends list to people they actually know. None of these reasons will be visible to you.
Frequently Asked Questions
Can I see a list of everyone who unfriended me?
Not directly from Facebook. Browser extensions can show you who unfriended you if you have them installed and running, but Facebook itself doesn't provide a list. You have to check manually or use a third-party tool.
Does the person know I found out they unfriended me?
No. Facebook doesn't notify them that you visited their profile or tried to add them again. They won't know you discovered the unfriending unless you tell them or message them about it.
Is it safe to use browser extensions to track unfriends?
Extensions from the official Chrome Web Store, Firefox Add-ons, or Edge Add-ons are generally safe, but read the reviews and permissions first. Avoid extensions from unknown sources. Some extensions store your friends list on their servers, so check their privacy policy before installing.
What's the difference between unfriending and muting?
Muting hides someone's posts from your feed without removing them from your friends list — you're still friends, but you don't see their updates. Unfriending removes them from your friends list entirely. The person won't know you muted them, but they might notice if they check whether you're still friends.
Can I block someone without them knowing?
When you block someone, they can't see your profile or message you, but they may figure it out if they try to visit your profile or search for you. Facebook doesn't send a notification that you blocked them, but the block itself is visible if they look for you.
