User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:66.0) Gecko/20100101 Firefox/66.0
Steps to reproduce:
browse to https://customer.comcast.com.
Actual results:
SEC_ERROR_UNKNOWN_ISSUER.
looks like COMODO RSA cert chain is not recognized. (see screenshot)
Expected results:
page loads.
worth noting that i tried in chrome and it works as expected, so i'm assuming it's not that the CA chain isn't being sent. (like other bug reports mention)

Attachment 9063602 [details] shows https://api.comcast.com If I try to load that, seemingly no content loads. Browser Console shows the server responds with 404 Not Found but the address bar icon doesn't show any certificate issues.
https://customer.comcast.com fails to load with no error code and no Advanced button to reveal it. In Nightly, the error code is PR_CONNECT_RESET_ERROR. Same thing in Vivaldi: error code ERR_CONNECTION_RESET, so this appears to be a site problem.
It's not sending any intermediate certificates: https://www.ssllabs.com/ssltest/analyze.html?d=customer.comcast.com
Firefox will handle this situation better once bug 1548365 ships, but in the meantime this can be an evangelism bug (they need to fix their server).

The bug has a release status flag that shows some version of Firefox is affected, thus it will be considered confirmed.

Currently, I'm getting "Expired certificate" both on Firefox and Chrome.
