I did a quick search of the source code for firefox, and it appears
that they implement their own internal version of tls, and they
support up to tls 1.3, if allowed, and fall back to up to 1.2 if 1.3
is disabled. So, it is unlikely that it is the protocol that is
causing the problem. If it was causing it on your system, it would
be causing it on mine.

Version : 52.0.2
Release : 2.fc25
Further research finds this page
https://en.wikipedia.org/wiki/Comparison_of_TLS_implementations
that says that nss and openssl also implement tls 1.2. And there
doesn't appear to be a tls 1.3, that must just be firefox preparing for
the future.
