ASP.NET Core Self Signed Certificate in Firefox not working

Question

I'm using the Self Signed Certificate in ASP.NET Core with is default on as noted in this article I have trusted it with the command dotnet dev-certs https --trust

In Chrome and Edge, my API is showing 'Connection secure' in green when calling it. However, in Mozilla Firefox (Quantum 61.0.1), it is giving 'Connection insecure' with the following error: MOZILLA_PKIX_ERROR_SELF_SIGNED_CERT

How can I solve this? How can I configure Firefox to allow Self Signed Certs? Or is this something I have to do in code?
