I would be happier if we called this "ForceSafeSearch" or something. "Enabled"
sounds like the possibility of using SafeSearch (and conversely, setting the
policy to false would imply that SafeSearch can't be used, when in reality it
just means that it's not enforced).

Done.

SafeSearch is not a Google Chrome feature, it's a Google feature. Remove the
<ph> element and just write Google in its place.
