On my local environment (https://app.dev) based on Windows -> Docker -> Apache 2.4, the new version of Firefox (59) blocks the self signed certificate. (It works fine until this version)
The message returned is:
app.dev uses an invalid security certificate.
The certificate is not trusted because it is self-signed.
Error code: SEC_ERROR_UNKNOWN_ISSUER
and I can't add an Exception.
If you have the same problem, your help will be welcome.
