title: Can't find serviceWorker in navigator anymore
body: <p>since the new update of Google Chrome (version 69.0.3497.92 (official build) (64-bit)) I can't find the serviceWorker service in the Navigator anymore. Actually I could register my Service Worker as follows but now I get an error that serviceWorker cannot be found in the navigator:</p>
  
  <pre><code>if('serviceWorker' in navigator) {
      /*
      *
      * Register the Service Worker
      *
      * */
      navigator.serviceWorker.register('sw.js').then(function(registration) {
          console.log('Service Worker Registered');
      });
  
  } else console.log('Your browser does not support the Service-Worker!');
  </code></pre>
  
  <p>How can I now use the Service Worker again, or how can I get it to run again for all Chrome versions?</p>
