title: Can you use a service worker with a self-signed certificate?
body: <p>I have developer server that are used for testing. They have SSL self-signed certificates, which allow us to test the web application over HTTPS, but with prominent warnings that the certificates are not verifiable.</p>
  
  <p>That's fine, but I have a Service Worker that throws an error with the <code>navigator.serviceWorker.register</code></p>
  
  <blockquote>
    <p>SecurityError: Failed to register a ServiceWorker: An SSL certificate error occurred when fetching the script.</p>
  </blockquote>
  
  <p>How do I use a Service Worker with an intranet testing server which has a self-signed certificate?</p>
