title: Firefox navigator get blocked because navigator.appName does not contains "Microsoft Internet Explorer", how to hack this?
body: <p>A stupid application blocks my Firefox navigator because navigator.appName does not contains "Microsoft Internet Explorer".</p>
  
  <p>I want the javacsript code <code>navigator.appName</code> to retrun something containing  <code>Microsoft Internet Explorer</code> instead of the w3c standard <code>Netscape</code>.</p>
  
  <p>The option <code>general.useragent.override</code> does not change the answers and have some border effects.</p>
