title: Google Chrome Extensions - Open New Tab when clicking a toolbar icon
body: <p>How can I create an extension for Chrome that adds an icon to the toolbar, and when you click it, it opens a new tab with some local web page (for example: f.html)? </p>
  
  <p>I saw <a href="https://stackoverflow.com/questions/2412258/chrome-extension-onclick-extension-icon-open-popup-html-in-new-tab">this question</a>, but it doesn't really explains what should I add in the manifest file...</p>
