title: The `--disable-web-security` command is seems no longer working
body: <p>The command <code>--disable-web-security</code> to allow for cross domain requests on Chrome is no longer working, I presume due to the latest update. </p>
  
  <p>Is there a workaround for this, besides downloading an older version of chrome and disabling updates?</p>
  
  <p>Might as well ask in the same question, the javascript snippet suggested to turn off web security in Firefox never works for me:</p>
  
  <pre><code>try {
      netscape.security.PrivilegeManager.enablePrivilege("UniversalBrowserRead");
  } catch (e) {
      alert("UniversalBrowserRead failed");
  }
  </code></pre>
  
  <p>The page always alerts <code>UniversalBrowserRead failed</code>.</p>
