Cp3p0 gave kudos to itman in ESET replacing site EV SSL certificate with its own?!?
Actually it does.
Firefox, Chrome, and Edge all recognize Eset root CA certificate. Otherwise, they would be alerting about it. All FireFox is informing about is the certificate is not one contained within their own internal root CA certificate store. FireFox now defers to the Win root CA certificate store in this situation which does contain Eset's certificate.
