Selenium + HTTPS + Firefox
These two links were invaluable:
Create a new Firefox profile (firefox.exe -profileManager). In this case the name of the new profile is selenium-https-profile.
java -jar selenium-server.jar -firefoxProfileTemplate
Dealing with self-signed SSL certificates when running Selenium server with Firefox:
Delete everything in the directory except for the cert_override.txt and cert8.db files.
