I am using the NSS certutil.exe app command line to add a self-signed certificate to Firefox. Using the command line I'm able to get my certificate to show up in the Certificate Manager under the "Authorities" and "Others" tabs. I have even gotten it to show up in the "Servers" tab. However, when it does the "Server" column has a "*". When I navigate to my website I still get a certificate warning. I noticed that when I manually add the exception the "Server" column says the name and port of my site. It seems to be different in other was too as the "Edit Trust" button seems to be permanently disabled. So, how can I "Add Exception" using NSS tools? I'm able to get the cert installed in a way that doesn't work using this command: certutil.exe -A -n "localhost" -t "P,P,P" -i "C:\<<Path to Cert dir>>\localhost.pem" -d "C:\Users\<<User>>\AppData\Roaming\mozilla\firefox\profiles\<<rand>>.default" Am I just missing a command line option? Any help or ideas would be appreciated! Thanks, EV
