* This script disables Youtube's autoplay feature on the new 2017 material design page.
* The new design is currently in test and will not be shown to every user.
* To enforce Youtube's new material design run the command below in the console and reload the page.
* document.cookie="PREF=f6=4;path=/;domain=.youtube.com";
*
* This script will also disable autoplay on Youtube's previous page (prior to 2017).
*
* Bonus: To hide the cookie consent header uncomment setCookieConsentHideCookie(); below.
