title: Is there a way to edit a chrome extension manifest file from within the extension?
body: <p>I want to allow the user to select the icon that appears for their extension from a list. Is there a way to edit the manifest from within the extension?</p>
  
  <p>So If I have the following in my chrome extension manifest file:</p>
  
  <pre><code>  "browser_action": {
      "default_icon": "ico32.gif",
    }
  </code></pre>
  
  <p>And I want to give the user the ability to change it to the following from within the extension itself:</p>
  
  <pre><code>  "browser_action": {
      "default_icon": "ico32green.gif",
    }
  </code></pre>
  
  <p>Is there a way to do that?</p>
