--- Comment #2 from Jan Beich <jbeich at FreeBSD.org> ---
Try disabling PGO option.

I only remember PGO working when Firefox could be built with base GCC 4.2.
Later GCC versions from ports had some issues with libgcov symbols. After
FreeBSD switched to Clang *and* libc++ the latter made using GCC hard because
GCC defaults to libstdc++ which is dangerous[1] to use with dependencies built
against libc++ (e.g., hunspell). Clang supports PGO (in FreeBSD 11.0+) but the
flags are a bit different[2].
