title: How to reload background scripts?
body: <p>According to MDN,</p>
  
  <blockquote>
    <p>Background scripts are loaded as soon as the extension is loaded and stay loaded until the extension is disabled or uninstalled. </p>
  </blockquote>
  
  <p>My background script changes its behavior accordingly user’s options, stored on localStorage. When the user change options (using <code>options_ui</code>), localStorage is updated, but since the background script stay loaded, user options are not honored. If the browser is reloaded, options are honored.</p>
  
  <p>How do I reload the background script after the user change options?</p>
