@90ninety If your looking to block adult domain names, you can also add one of the Chad Mayfield lists. They're under Firewall > pfBlockerNG > Feeds > Firebog_Other (all the way at the bottom of the feeds list). There are two you can choose from.
I have the same problem but also my google home is blocking, i have added some IP adresses of google but not helped me.
Anyone a suggestion about that? I think i am not the anyone that this problem have with Google services.
