I am on Kubuntu 20.10. I managed to export my keys from gpg in an armored text format, and import them in Mozilla Thunderbird, both the public and the private key. Is there a way to avoid this process, and have Mozilla Thunderbird communicate with gpg directly? I noticed that, when I encrypt a message, Mozilla Thunderbird doesn't ask me the password for the private key. So I assume Mozilla Thunderbird stored it somewhere. Where does Thunderbird store my password for the private key, and is it saved in plain text? I don't want it to be stored in plain text
