Not using ipfw by myself, but according to the handbook, the modules are
loaded automatically, when editing rc.conf to load the firewall:

IPFW is included in the basic FreeBSD install as a run time loadable
module. The system will dynamically load the kernel module when rc.conf
contains the statement firewall_enable="YES". After rebooting the
system, the following white highlighted message is displayed on the
screen as part of the boot process:

ipfw2 initialized, divert disabled, rule-based forwarding disabled,
default to deny, logging disabled
