title: Firebase deactivate non-realtime mode
body: <p>I am getting this warning message at firebase console:</p>
  
  <pre><code>Read-only &amp; non-realtime mode activated to improve browser performance 
  Select a key with fewer records to edit or view in realtime
  </code></pre>
  
  <p>How can I activate back the real-time mode? This is getting out of hand as I could not delete any node right now. </p>
  
  <p>Thanks!</p>
  
  <p><strong>UPDATE</strong></p>
  
  <p>By right the last 3 attributes are auto expanded in real time mode. Currently they are collapsed by default. Also, I could not delete the entire 'accounts' node in this case. If it is in the real time mode, I could do so.</p>
