When I step on the DHCP generated /etc/resolv.conf from
Comast with one using my Wireless router as my primary
resolver, the performance of Firefox jumps dramatically.

Both the router and the DHCP generated /etc/resolv.conf
have the same DNS server entries.

DNS should be the first item to be checked.
