title: Why do contents only show up for one user at a time while using firebase authentication?
body: <p>I want to know why do contents only show up for one user at a time.  </p>
  
  <p>For example: if <code>personA@gmail.com</code> is logged in, uploads a file on the browser with the intention that other users are able to see it and  afterwards, <code>personA@gmail.com</code> decide to logout for whatever reason.  Now, <code>personB@gmail.com</code> logs in.  How can you make it where, when logged in, <code>personB@gmail.com</code> can see the content <code>personA@gmail.com</code> uploaded (the file)?</p>
  
  <p>I'm not too sure what to search hence why I'm asking this here.</p>
  
  <p>Security file below:</p>
  
  <pre><code>service firebase.storage {
    match /b/{bucket}/o {
      match /{allPaths=**} {
        allow read, write: if true;
      }
    }
  }
  </code></pre>
