Bounty: 100

I set up Thunderbird to use PGP a while ago, so I can sign and decrypt messages now. But I have forgotten my private passphrase for my private key, but since Thunderbird can do it anyway, it has it stored somewhere. How can I get it?

I already know that the password, with which encrypted-openpgp-passphrase.txt – the file that actually has my forgotten passphrase – is encrypted, is stored in key4.db, but I were unable to figure it out by reading key4.db – both with a SQLite browser and with cat. The program firefox-decrypt is not helpful since it only gives me the login credentials for my e-mail-server.
