/*
 * If you're on Firefox, you might have noticed that when you try to click (or copy) a link from
 * a google search result, it redirects to an intermediate page instead of taking you immediately
 * to the search result. This is specifically annoying when trying to copy a google search result
 * to send to someone else, because it gives you the mangled google-ified link instead.
 * 
 * The same does not happen on Google Chrome or other chromium browsers. Maybe someone can test
 * this on Safari?
 * 
 * To install this script, you'll need a user script manager like ViolentMonkey, after which you
 * can click the Raw button (gist.github.com) to install.

   * 
   * On testing, this does not seem to break any actual functionality on the site.
