How do I stop the "attempted to access these secure websites" popup with parental controls enabled?

This makes parental controls almost unusable. Nearly every website tries to access numerous other domains that are not in my whitelist. Is there any way to just stop all prompts to add items to the whitelist? It could remain static and just block everything and I'd be happy (kind of thought that was the purpose of parental controls and whitelisting to begin with). Young kids have no idea what to do with these windows popping up.

Thanks!
