1464059 - Firefox rejects Github's cert for tom--.github.io

Status: RESOLVED DUPLICATE of bug 1184059

(Core :: Security: PSM, defect)

Description

[Tom]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.13; rv:60.0) Gecko/20100101 Firefox/60.0
Build ID: 20180516032328

Steps to reproduce:

I tried to load https://tom--.github.io/yii2-dynamic-ar/


Actual results:

SSL_ERROR_BAD_CERT_DOMAIN

https://tom--.github.io/yii2-dynamic-ar/ Unable to communicate securely with peer: requested domain name does not match the server’s certificate.

tom--.github.io uses an invalid security certificate. The certificate is only valid for the following names: www.github.com, *.github.com, github.com, *.github.io, github.io, *.githubusercontent.com, githubusercontent.com 


Expected results:

Firefox should accept the cert.

Google Chrome, Safari, Edge, Internet Exporer accept it.

Firefox used to accept it in previous versions, although I cannot tell you which. I don't know.

That's as far as mozregression-gui got me. It stopped with "Unable to find enough data to bisect."
