I've installed a custom CA certificate and made sure the trust was updated and added the certificate to Apache. For some reason Firefox doesn't want to accept it, even after I added the name of the domain directly in the alt_names without a wildcard (Hence the "imesa.alpha.kira" as the last record, which is a test) This works in Chrome without any issues, and used to work in Linux Mint 18.3 without issues (So older version of Firefox about a year ago). I've attached some screenshots to what I'm doing, this is all on a local server, but added ########### to location info in the cert config, this isn't normally part of it. Adding the imesa.alpha.kira domain to the common name does work, but I need multiple domains to work. I'm at a loss as to what could be causing this at this point. Any help is appreciated.
