/usr/share/mk/bsd.cpu.mk doesn't support CPUTYPE?=native :
% make -VMACHINE_CPU CPUTYPE=native
unknown amd64 sse2 sse mmx
% make -VMACHINE_CPU CPUTYPE=core2
ssse3 sse3 amd64 sse2 sse mmx

But you can use a supported value, add -march=native to your CFLAGS
and COPTFLAGS, and set NO_CPU_CFLAGS=yes and NO_CPU_COPTFLAGS=yes so
that another -march won't be automatically added.

And if you use the old base-system gcc, -march=native won't give
proper results with a Core2 and a Corei7 (not tested other recent
CPUs) because they'll use -mtune=generic instead of the good -mtune. I
prefer setting a proper -march.

I don't know if thta's related to your firefox problem though.

Cheers
