CA Signed Certificate shows as "not valid"
There is a certificate for an internal website that FireFox is saying is not valid/secure and it makes you add an exception. However, if you use IE, Edge or Chrome it loads fine with the valid CA Certificate. I've cleared all data (cache/etc...) and it hasn't fixed it. Hopefully someone has a fix for this?
Getting "SEC_ERROR_UNKNOWN_ISSUER" for the certificate and its saying:
Peer’s Certificate issuer is not recognized. HTTP Strict Transport Security: false HTTP Public Key Pinning: false
FireFox Version: 91.8.0esr (64-bit)
Operating System: Windows 10 (64-bit)

Firefox does not use the operating system certificate store by default.
Can you go to about:config and search for the preference
security.enterprise_roots.enabled
and change it to true and see if that fixes things?

So, that fixed it, thanks! But why would that matter? The certificate is loaded to the server itself. The certificate was not loaded to GPO, windows store or anything else. Only applied to the server itself.
My guess is that your company uses a custom certificate authority for that site (not a public one) and they load that CA into Windows expecting it to work.
That could be. Just not disclosed to us after its generated on specifically what they did. Thanks!
