Create a DNS ad blocklist in pfSense

The steps are 100% identical to the post about configuring the dns in IPCop (see this) with one extra step

Instead of:

vi /var/ipcop/dhcp/dnsmasq.local

Do this

vi /usr/local/etc/dnsmasq.conf

You will notice that this will create a new file if it's your first time. All other steps are identical (here).

Verified working on pfSense 2.1-RELEASE (amd64)
