title: Change navigator in browser to pretend, that plugin is installed (with javascript)
body: <p>I am trying to do Chrome extension, that will pretend, that some plugins are installed. I was trying to edit navigator.plugins, but these properties are read-only. I can add new item navigator.plugins[x], but I do not know, how to create new (Plugin, PluginArray or MimeType) objects in navigator.plugins.</p>
  
  <p>Is it even possible ?</p>
