Block Browser Legacy Extension Points

Setting the policy to Enabled or leaving it unset will permit Google Chrome to apply the additional extension point security mitigation to block legacy extension points in the Browser process. Setting the policy to Disabled has a detrimental effect on Google Chrome's security and stability as unknown and potentially hostile code can load inside Google Chrome's browser process. Only turn off the policy if there are compatibility issues with third-party software that must run inside Google Chrome's browser process.
