Yes, for NetBSD 7 and 8, firefox needs a newer version of GCC than the
base system provides, so you will end up with something like:

ldd /usr/pkg/lib/firefox/firefox

/usr/pkg/lib/firefox/firefox:
        -lpthread.1 => /usr/lib/libpthread.so.1
        -lc.12 => /usr/lib/libc.so.12
        -lstdc++.7 => /usr/pkg/gcc6/x86_64--netbsd/lib/./libstdc++.so.7
        -lm.0 => /usr/lib/libm.so.0
        -lgcc_s.1 => /usr/pkg/gcc6/x86_64--netbsd/lib/./libgcc_s.so.1

So perhaps what happened is the necessary gcc-libs package (e.g., in my
example above, gcc6-libs) didn't get pulled in for some reason.
