Unfriend Checker is a free Chrome extension that allows users to easily track who has unfriended them on Facebook. With just a few simple steps, users can find out if anyone has removed them from their friends list.

Upon installation, Unfriend Checker adds a red button to the Facebook page. By clicking on this button, the extension checks the user's Facebook friends list and compares it with a previously saved list on their server. If there are any discrepancies, it indicates that the user has been unfriended.

The simplicity and ease of use make Unfriend Checker a convenient tool for those who are curious about their Facebook connections. Whether you want to keep track of who has unfriended you or simply satisfy your curiosity, this extension provides a straightforward solution.

Please note that Unfriend Checker is an add-on and can only be used with the Google Chrome browser.
