Google introduced a new experimental
Strict site isolation mode feature in
Google Chrome 63.
Google’s
site isolation feature improves security for Chrome browser users. When you enable site isolation, content for each open website in the Chrome browser is always rendered in a dedicated process, isolated from other sites. This creates an additional security boundary between websites.
Strict site isolation is not enabled by default in Chrome, but is available as an experimental flag.
If you enable site isolation, it will come at the expense of additional memory requirements for the improved stability and security. Memory usage can increase by approximately 10–20% depending on how the browser is used.
This tutorial will show you how to enable or disable the
Strict site isolation mode feature in
Google Chrome for your account in
Windows 7,
Windows 8, and
Windows 10.
