$ xset q

It will show you the 'Font Path' used by X, among other information.

I'm using firefox-70.0_3,1 on 11.3-STABLE installed from ports,
and it displays the map on that web site correctly. webfonts package is
not installed.

When dealing with firefox problems, it's always suggested to run it
with the --ProfileManager command line option, create a new profile and
test under that new profile (without touching any configuration).
In your case I would also consider creating  new user account
(pw useradd) just to debug this issue.
