portupgrade doesn't build ports in a clean environment which means you
have a chance to accidentally end up with mixed/partial upgrade where
dependencies don't match what firefox was built against. If you can't
build the whole package set against a single ports tree revision try
replacing packages one by one with those from pkg.freebsd.org until
firefox stops crashing.

Alternatively, try Firefox 63 just in case there's an upstream bug.

These are... already default. I regularly test inside 10.4 jail but
mainly on i386 because amd64 is already overtested enough.

core(5) files are near useless without symbols but FreeBSD doesn't have
central symbol server nor packages symbols separately. You'd have to
build Firefox itself and many library dependencies with symbols e.g.,

  $ readelf -d /usr/ports/.local/lib/firefox/libxul.so | fgrep NEED
