title: Selenium ChromeDriver - Remember "Always Allow" setting for getUserMedia webcam access
body: <p>I've got a page running on a local webserver, on an https page, that uses the getUserMedia API to do some photobooth-style webcam stuff.</p>
  
  <p>In ChromeDriver, the browser won't remember the "Always allow" setting for allowing webcam access. I'm given the option, and it remembers that preference while the browser's running, but once I quit/re-open, the prompt returns.</p>
  
  <p>I'm running Chromedriver 26.0.1383.0.</p>
  
  <p>Does anybody know how to make that preference stick around permanently?</p>
