How to add multiple email addresses under one OpenPGP key?
I have an email account with multiple identities (aliases), some of which I would like to add under the same OpenPGP key that I'm using for the main identity. I couldn't find any option in the OpenPGP Key Manager in Thunderbird which would allow me to add identities to the key. How should I go about doing this?

You will have to use GPG directly outside of Thunderbird in order to add additional identities to your key. Assuming GPG is already installed on your device with your secret key imported, you can use the gpg --edit-key $YOUR_KEY_ID adduid command to add another identity to your key and then import it back into Thunderbird.
