YouTube being allowed in Chrome via Google searches, despite being blocked as a Category or List Rule


When a user makes a Google search containing YouTube (such as “youtube facebook channel” or “youtube cat videos”) Google will return video previews along with the typical links/URLs. 

If the browser is Chrome, when the user hovers over these video previews Google will pre-load the video into the browser’s cache with a URI like “”.  Then if the user clicks on the video, we don’t see a request (and can’t block it).

In order to prevent this, do not create any white-list rule for or *

If you see this behavior, it is recommended that you perform a list audit for these URI’s and assess if updating these URIs will resolve this.
