Last month, I introduced LikeBuster, a simple JavaScript routine intended to unobtrusively reduce unwanted spam in your Facebook feed. I have been steadily updating and enhancing the core functionality of this script, wrapped within a Chrome extension. Today, I have ported that script over to a Firefox extension as well. While the add-on undergoes review, feel free to directly download the .xpi at the LikeBuster GitHub page. Special thanks to my friend Anish for reminding me that people still use Firefox, and giving me an excuse to learn how to write extensions for it.
