title: How to automatically clear chrome.storage
body: <p>My Chrome extension stores some data using <code>chrome.storage</code>, &amp; fetches the results from the storage as needed.</p>
  
  <p>However, I realize now that I need to periodically need to refresh the data in <code>chrome.storage</code> - which means clearing it from time to time.</p>
  
  <p>Is it possible to:</p>
  
  <ol>
  <li><p>Have Chrome treat <code>chrome.storage</code> as <strong>Session</strong> storage - that is - it clears the data once the browser closes?</p></li>
  <li><p>If above is not possible, is <code>chrome.storage.remove</code> the only way to clear storage?</p></li>
  <li><p>What happens when the <code>chrome.storage</code> space hits its limit?</p></li>
  </ol>
