title: Persistent Service Worker in Chrome Extension
body: <p>I need to define my Service Worker as persistent in my Chrome extension because I'm using the webRequest API to intercept some data passed in a form for a specific request, but I don't know how I can do that. I've tried everything, but my Service Worker keeps unloading.</p>
  <p>How can I keep it loaded and waiting until the request is intercepted?</p>
