k3a / Disable private events

// ==UserScript==
// @name         Disable private events
// @namespace    http://tampermonkey.net/
// @version      0.1
// @description  This disables events which most normal websites shouldn't need (mouse events, key up and down, etc).
// @description  These events leak private information and overrides are annoying (websites prevents right-clicks).
