Allowing self-signed certificates on Firefox

Has anyone had problems accessing their local rack through Firefox? I get a self-signed certificate warning, but when I add an exception, it just takes me back to the same warning page, even though the exception is tracked in the settings page. Tried wiping my Firefox settings but it didn’t help. Chrome has no issues. Not sure what kind of docker/dns magic is happening under the hood for the *.convox domains resolve. (Firefox 56.0)

You can enable support for it in about:config by toggling on security.enterprise_roots.enabled

Appreciate it. Sent a PR to add this to the docs.
