title: Automatically fill multi-page forms in chrome extension
body: <p>I'm working on a cross-pages webform autofill project. Now I can use popup to get data produced by background.js, and then send message to content.js to fill the first page form. However, when progrmatically clicked the &quot;save and continue&quot; button to another page, nothing happened.</p>
  <p>Anyone has some ideas about what happened after the click and how to work it out. Thanks.</p>
