The elswhere-discussion suggested it was used only during build, so if
the build succeeds this particular problem would not be relevant to
firefox on -current. I am building it right now after a different
problem was quickly resolved. I don't know how nodejs is used during
the build.

The comments in lang/nodejs indicate that the maintainer has left the
built-in openssl to be used, as our security/openssl package is still
on 1.0.2, whereas nodejs requires at least 1.1. I couldn't find an
obvious way to make the nodejs use the built-in system delivered
openssl 1.1.1, which should be good enough for it.
