title: How can I browse with localstorage disabled?
body: <p>A site I'm building uses localstorage with a fallback to php sessions.</p>
  
  <p>How can I test my website in a localstorage free environment <strong>without downgrading Firefox, Internet Explorer 8, Chrome or Safari?</strong> So I'm probably looking for an add-on for one of these browsers?</p>
  
  <p>I've tried ie7 mode in ie8 - no joy :(</p>
