Hello, This is my first time posting to this list, so if there is a better way to do this please tell. :)
(tested on current with the provided package and nothing else installed) It looks like the <https://trac.torproject.org/projects/tor/ticket/18097> Font fingerprinting defenses from upstream don't work in the OpenBSD port. When checking for the fingerprint on one of the websites that do such a thing, it seems like the installed fonts property is not uniform with tor browser on other platforms, but instead unique to OpenBSD and this port. It lists some specific proprietary font names (including Helvetica, which I would assume we don't ship in base, but some free replacement) and therefore makes users of the OpenBSD tor browser distinct from every other tor browser user. This is a bug. I thank everyone involved with the port and hopefully we can send fixes required upstream.
