Remove reaction and like notifications, counters, and buttons from Facebook.Unlikeable removes reaction and like notifications, counters, and buttons from all Facebook webpages. You can configure whether to remove each of the three elements (notifications, counters, buttons) separately in the Options. That's it!
Tech details for programmers:
This extension uses pure CSS to hide elements, with JavaScript only to manage options and load CSS according to them. The options page uses JQuery 3.1.1 but the content script itself uses only pure JavaScript and a handful of CSS rules, so it's extremely lightweight. The code is open-source on GitHub and contributions are welcome: https://github.com/jchang504/unlikeable
