The company revealed today that it has enabled Site Isolation in 99% of all Chrome installations for the desktop as of Chrome 67. The remaining 1% of installations without Site Isolation is used as a control group to monitor performance and issues.
Google plans to enable Site Isolation in Chrome for Android but has yet to reveal the version it plans to turn the security feature on by default.
Enterprise users may use policies to enable Site Isolation starting in Chrome 68 for Android, and there is also a manual option to turn the feature on right now.
Android users who run Chrome on the device may enable Site Isolation in the browser.
Note that Site Isolation increases the memory usage of the browser and that Google mentioned that it has to address known issues that still exist. Google did not reveal what those issues are that are specific to Chrome on Android. It is easy enough to turn off Site Isolation should you run into these issues.
So, here is how you enable the security feature in Chrome for Android:
Site Isolation is enabled in Chrome for Android after the restart. You can turn the feature off again by setting the flag to disabled and restarting Chrome. It is best to use Chrome as you normally would to make sure all sites and services work as expected.
There is no blacklist functionality available which means that your only option is to disable Site Isolation if you run into critical errors.
Site Isolation increases the memory usage of Chrome as it makes use of more processes. Google's own benchmarks saw memory usage increase by about 10%-13% on the desktop with Site Isolation enabled.Advertisement
