There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connection certificates and send their own.

What do the security warning codes mean
- MOZILLA_PKIX_ERROR_MITM_DETECTED
- uses an invalid security certificate SSL_ERROR_BAD_CERT_DOMAIN
- configured their website improperly
How to troubleshoot the error code "SEC_ERROR_UNKNOWN_ISSUER" on secure websites https://support.mozilla.org/en-US/kb/troubleshoot-SEC_ERROR_UNKNOWN_ISSUER
The issuer of the certificate is Cisco Umbrella.
- Issuer: CN=Cisco Umbrella Secondary SubCA nrt-SG, O=Cisco
You can set this pref to true on the about:config page in case other software adds its root certificate to the Windows certificate store.
- security.enterprise_roots.enabled = true
You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.
The certificate likely is associated with the OpenDNS service companies can use to control use of social media through their networks. If YouTube is essential to your work, your IT department likely can disable that feature.
