Would you like to know when someone "unfriends" you on Facebook? There's not a native way to see this information, and unless you keep a very close eye on your friend list, it's likely when your friend count goes down, you aren't sure who went missing.
We have found a simple script that works with Firefox, Google Chrome, Opera and Safari that notifies you when someone on Facebook unfriends you, alerts you when someone you're friends with deactivates their profile, and helps keep track of your friend requests.
