firefox - Programmatically Install Certificate into Mozilla

Question

Is there a way to programmatically install a certificate into mozilla? We're trying to script everything to eliminate deviations in environment so installing it by hand through mozilla preferences does not work for our needs. I assume theres a way to do it with certutil, but I am not sure of Mozilla's internals, etc.

Answer 1

Here is an alternative way that doesn't override the existing certificates: [bash fragment for linux systems]

certificateFile="MyCa.cert.pem"
certificateName="MyCA Name" 
for certDB in $(find  ~/.mozilla* ~/.thunderbird -name "cert8.db")
do
  certDir=$(dirname ${certDB});
  #log "mozilla certificate" "install '${certificateName}' in ${certDir}"
  certutil -A -n "${certificateName}" -t "TCu,Cuw,Tuw" -i ${certificateFile} -d ${certDir}
done

You may find certutil in the libnss3-tools package (debian/ubuntu).
