I am getting error www.mozilla.org uses an invalid security certificate.
The certificate is not trusted because the issuer certificate is unknown. The server might not be sending the appropriate intermediate certificates. An additional root certificate may need to be imported. Error code: SEC_ERROR_UNKNOWN_ISSUER

Peer’s Certificate issuer is not recognized.

Thanks for the encoded certificates. So the “fake” website cert was issued by:

“Forcepoint Cloud Web Enforcer CA”

Does that sound like some security filter that limits what you can do on the web? If you want to trust all of its fake certs, you can import the signing certificate. I’m not sure if this is readily available on your system or from your administrator or from the vendor, or whether you’ll need to extract it using IE or another browser. As a temporary workaround, you could try this and see whether it helps:

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button promising to be careful or accepting the risk.

(2) In the search box above the list, type or paste roots and pause while the list is filtered

(3) Double-click the security.enterprise_roots.enabled preference to switch the value from false to true

Now Firefox should trust the certificates in the system certificate store. On the downside, that means if your system is attacked and a fake authority is added there, Firefox is no longer insulated from that.

Thanks for your solution. It works. :relieved:
