Installing and upgrading are two different activities in pkgsrc.
There's a bunch of different ways to do it - see:

http://www.dragonflybsd.org/docs/howtos/HowToPkgsrc/#index4h2

I recommend pkg_rolling-replace in general when building from source.
Off the top of my head, this should mark firefox for rebuilding and
then rebuild it and all its dependencies.

pkg_admin set rebuild=YES firefox
pkg_rolling-replace -rsv

You can then tackle other packages for upgrades as you like or run
'pkg_rolling-replace -uv' to rebuild everything.  I'm writing from
memory, so check the man pages for these tools and get an idea for
what they do before you copy and paste anything I typed.
