title: Firebase Authentication in a Chrome Extension Background Page
body: <p>How would I authenticate with Firebase in a chrome extension? I need to specify the allowed domain list in the Forge. Chrome domain for the extension is just a big hash-like string.</p>
  
  <p>I did read this: <a href="https://stackoverflow.com/questions/14299364/authclient-login-problems">authClient.login problems</a></p>
  
  <p>But the hashed based domain of a chrome extension is not being accepted in the Firebase forge. Is there another way to go about it? Currently am just reading the cookie <code>firebaseSessionKey</code> to just assume that I am logged in. But surely that can't be as secure as letting Firebase validate this session key.</p>
