When you turn on site isolation, Chrome offers more security protections for your browser.

Chrome will load each website in its own process. So, even if a site bypasses the same-origin policy, the extra security will help stop the site from stealing your data from another website. Learn more about site isolation.

To set up isolation:

  1. On your computer, open Chrome.

  2. In the address bar at the top, enter chrome://flags/#enable-site-per-process and press Enter.

  3. Next to "Strict site isolation," click Enable.

  • If you don't see "Strict site isolation," update Chrome.

  1. Click Relaunch now.

If you’re an administrator, learn how to manage site isolation for your organization.

Known issues

  • Memory: Site isolation will increase Chrome's memory use by approximately 10–20%.

  • Printing: Cross-site iframes will be blank. To print the entire page, save the page to your computer. Then, open and print the saved file.

  • DevTools: Chrome Developer Tools don't fully support cross-site iframes with site isolation.
