Answer 1

edit: it's not necessary to use the nightly firefox anymore

Rémi's answer is correct, thank you. I have been facing the same issue in Java, in case someone else stumbles across this here's the Java solution:

DesiredCapabilities caps = DesiredCapabilities.firefox();
caps.setCapability("acceptInsecureCerts", true);

FirefoxDriver driver = new FirefoxDriver(caps);

there isnt a CapabilityType.ACCEPT_INSECURE_CERTS yet as per Selenium version 3.3.1 and the CapabilityType.ACCEPT_SSL_CERTS doesn't work, thus use "acceptInsecureCerts". Also the constructor FirefoxDriver(binary, profile, capabilities) is deprecated but AFAIK this is the only way to use a custom Firefox binary (?).
