Strict Site Isolation Enable Chrome on 63

Google Chrome 63 released yesterday, brought a new experimental feature called Strict Site Isolation.

According to Google developers it is an additional level of security in its built-in sandboxing technology Chrome.Strict Site Isolation

Google developers didn't explain the complex differences between Chrome sandbox and Site Isolation, but according to , the Strict Site Isolation feature puts "even stronger security boundaries between websites and Chrome's sandboxing technology."

However, this function is not activated by default. The reason is that Google is still working on improving the feature. It also states that those of the browser users who activate the function in Chrome 63, "will increase memory usage by approximately 10-20%".

If using the above memory is not a problem for you, below we will see two ways to activate Strict Site Isolation.

Via Chrome flags

Type chrome: // flag and press Enter.


Find the "Strict isolation site" and press the Enable button. Alternatively, copy and paste the following URL into the Chrome address bar:

chrome: // flags / # enable-site-per-process

Restart Chrome.

Via Shortcut

Find the Google Chrome icon or shortcut and double-click it
Select Properties
From Συντόμευση, στο πεδίο Προορισμός, προσθέστε το ακόλουθο κείμενο “–site-per-process” στο τέλος της διαδρομής της and press Apply and OK.
