As noted in the Release Notes of Firefox 52.0 [1], released March 7, 'Display (but allow users to override) an “Untrusted Connection” error when encountering SHA-1 certificates that chain up to a root certificate included in Mozilla’s CA Certificate Program.'
So, it applies to all certs that have "AC Componentes Informáticos" in the cert chain. Untrusted Connection error with code: "SEC_ERROR_CERT_SIGNATURE_ALGORITHM_DISABLED" is expected on all websites that have certs like https://www.edu.xunta.es/webmail/ (referenced before). Users may feel they have the same error like before Firefox 51.0. The only and unique version of Firefox where certs like this one works, is 51.0, released January 24, which was updated to NSS 3.28.1. [1] https://www.mozilla.org/en-US/firefox/52.0/releasenotes/ (Websites that have certs with "AC Administración Pública" in the cert chain ARE NOT impacted, as "AC Administración Pública" is signed with SHA-256.
