title: How to disable Site Isolation in Google Chrome?
body: <p>Chrome 67 has enabled <a href="https://security.googleblog.com/2018/07/mitigating-spectre-with-site-isolation.html" rel="noreferrer">Site Isolation</a> on Windows, Mac, Linux, and Chrome OS, which increases memory usage by 10-13% and introduces some problems for web developers:</p>
  
  <ul>
  <li>Full-page multi-frame layout is no longer synchronous, since the frames of a page may be spread across multiple processes,</li>
  <li><code>beforeunload</code> event handlers are not working in cross-site subframes and <code>unload</code> event handlers may have issues with <code>postMessage</code>,</li>
  <li>DevTools' Network panel does not show cookies and other request headers for cross-site subresource requests.</li>
  </ul>
  
  <p>I want to save RAM more than extra security. How to disable Site Isolation?</p>
