Unlikeable is a free Chrome extension developed by jchang504 that allows users to remove reaction and like notifications, counters, and buttons from Facebook. With Unlikeable, you can customize your Facebook experience by choosing which elements to remove, including notifications, counters, and buttons.

The extension utilizes pure CSS to hide the unwanted elements, while JavaScript is used to manage options and load CSS based on user preferences. Unlikeable is designed to be extremely lightweight, with the content script using only pure JavaScript and a few CSS rules. This ensures that the extension does not slow down your browsing experience.

For developers, the code for Unlikeable is open-source and available on GitHub. Contributions to the project are welcome, allowing for continuous improvement and customization. If you're tired of seeing reaction and like notifications on Facebook, Unlikeable provides a simple and effective solution.
