  <p>After clicking the URL on Google Chat, I want to use another web browser instead of Google Chrome.
  How do I use a different web browser instead of Google Chrome?</p>
  <ul>
  <li>Click the URL on Google Chat → I want to start Firefox.</li>
  <li>Click the URL on Google Chat → I don't want to start Google Chrome.</li>
  </ul>
  <p>that's all.</p>
