title: WebGL just stopped working locally for no reason
body: <p>I was playing with some WebGL tutorials and, for no reason, WebGL just stopped working.  I even loaded an untouched WebGL HTML page that I downloaded from the web that worked fine before.  When I FTP that same exact code to my web server and load it, it works fine.  Two questions...</p>
  
  <ol>
  <li>Why would WebGL all of a sudden just stop working locally across ALL browsers?</li>
  <li>Why would WebGL HTML code run fine online, but not locally?</li>
  </ol>
  
  <p>I should also mention I restarted my computer, uninstalled/reinstalled Chrome and Firefox, and cleared all my internet cache.</p>
  
  <p>Thanks so much for all your wisdom!</p>
