After tried to to add url for blockage with Privatefirewall 'URL > Host Name: ambr.net' and then checked the URL/IP Address' list and 'exported settings', we could not find it added. We already have over 300 URL and IPs on that list. Is there a limit to the number on the list, and/or is there a particular problem with the ambr.net url ? Usually it seems to ask for an IP address if there is a problem with the URL but not for this one. Thoughts ?
