Norton Online Family

Norton Online Family won't block facebook.com. I have blocked Social Networking, Online Chat. But it still lets my child on facebook. I have uninstalled and reinstalled Norton Safety Minder. But it still lets him on facebook. Facebook.com is in the list for blocked websites.

 

I get a notification: Browser Plugin Disabled. Don't know who disabled it, I was just on the account and it shouldn't be disabled.

 

Please can somebody help?

 

Thank you
