https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=223563 --- Comment #2 from Jan Beich <jbeich@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].
