Feel free to fill in the blanks. I didn't know how to break up some of the stuff in the GENERAL section but I was going for general site layout-type stuff under general but much of the general section is probably deserves better categorization (console API, WEBRTC, Crypto, etc.)
Note: This add-on's advantage over simply disabling features via about:config prefs is that the web site gets a more graceful response versus completely disabling a web feature that is typically expected in a modern web browser.
