Why is Symantec Class 3 Extended Validation SHA256 SSL CA no longer trusted

A certificate issued on 13th June 2017 with path :

Verisign Universal Certification Authority

Symantec Class 3 Extended Validation SHA256 SSL CA
  www.invescoperpetual.co.uk

Throws the SEC_ERROR_UNKNOWN_ISSUER error due to missing that Symantec intermediate. I can override and force the end user cert OK but want to know why that intermediate is missing. I think other Symantec intermediate issued certs work OK ... just the EV SHA256 flavor??. IE11 and Chrome both work OK. Firefox version is 54.0.1 (32 bit)

Firefox only comes with trusted root certificates. It is the responsibility of the web server to make sure to send all intermediate certificates.

It work if I import the Symantec Class 3 Extended Validation SHA256 SSL CA in the Firefox Certificate Manager.

You only get this error if the server isn't sending a complete certificate chain. When Firefox has stored the intermediate certificate in the Certificate Manager from an earlier visit to a website that sends this certificate then you wouldn't see this error. Firefox doesn't retrieve missing intermediate certificates like other browsers might do.

If you refresh Firefox then the cert8.db file that stores these certificates isn't transferred to the new profile.

I must be missing something. I thought that the list of trusted CA's both root and intermediate came with the Firefox browser installation and the unknown issuer message throws when the client browser doesn't find an issuer in the certificate chain provided by the server during https session initialization. Is that thinking wrong??
