title: Where do I edit manifest.webapp
body: <p>I'm using cordova to package my app, but I'm unable to modify a <code>manifest.webapp</code>, specifically adding icons, so that the changes are included when I run</p>
  
  <pre><code>cordova build firefoxos
  </code></pre>
  
  <p>I've tried to edit <code>platforms/firefoxos/www/manifest.webapp</code> but these changes are lost when I run <code>cordova build firefoxos</code></p>
