title: Firebase OAuth error when trying to set up sample web application
body: <p>I'm getting the following error message in my web browser</p>
  
  <blockquote>
    <p>firebase.js:75 Uncaught Error: This domain is not authorized for OAuth
    operations for your Firebase project. Edit the list of authorized
    domains from the Firebase console.</p>
  </blockquote>
  
  <p>I have downloaded the Firebase <a href="https://firebase.google.com/docs/samples/" rel="nofollow">web app sample</a> to my local machine, pastet the snippet from the firebase console into the .html file of the "database" sample project and enabled Google as authentication method in the console.</p>
  
  <p>Removing the snippet removes the error, but than it doesn't work at all (unsuprisingly).</p>
  
  <p>Also tried with the "auth" sample project.</p>
  
  <p>I have noticed there is a <a href="https://status.firebase.google.com/" rel="nofollow">service disruption reported</a> by Firebase, but unsure if that is the reason.</p>
  
  <p>What am I doing wrong?</p>
