If you wonder how to get HTTPS for your local virtual hosts:

1. create a local CA

2. create a certificate using that local CA

3. Then you can add the CA in your trusted authorities (Firefox does need an extra step: either enable the "security.enterprise_roots.enabled" flag, either import the CA certificate manually in it).
