Mozilla is using libnss to check the validity of the website certificate with 
the OCSP of the CA issuer of the certificate (digicert.com).  For some reason 
it seems the connection is interrupted.  See lines 605 to 621 here:

https://code.woboq.org/qt5/qtwebengine/src/3rdparty/chromium/net/cert_net/
nss_ocsp.cc.html

The connection may be interrupted because the browser/tab crashes (see below).

This looks like a radeon video driver problem.  You could go into a loop of 
rebuilding xorg, mesa, dev-libs/nss, what-ever and see if things improve, or 
you could wait for/keyword later versions of these packages.

Alternatively, you could try reporting this to the application devs and see 
what they say.
