Hi Solosuamor92
I do the exact same thing with the Firewall popups, I block them, because for the most part, you don't want applications having full access through you firewall, for the most part that is just so the applications can update in the background without annoying you with update popups, I still feel it is safer to block them on the firewall and update them manually when I choose to update them . . .
Public, means that app is allowed to access the Internet, Private means the app can only access a local network or Ethernet connection
