Replacement for host file win 11

[harryray33]

A couple of basic questions.

I built up quite a large extensive hosts file on Win 7, which amongst other things I used to deny various apps I was running from 'phoning home', unfortunately the hosts doesn't work on Win 11.
Does Portmaster act in a similar way to the hosts file? If it does it it possible to import entries from the hosts file into Portmaster?

Does Portmaster interfere with Ublock. I'm using firefox.

Thanks.
