Mozilla of today is run by designers, webheads and &quot;social&quot; personas.<p>As for encrypted email, it could be made very simple. When you set up an account in Thunderbird, have it ask a simple question &quot;do you have an encryption key?&quot;. If the user hits no, generate the key pair, and insert the public key by default.<p>Then starts harvesting public keys from incoming emails, and encrypt by default if sending to an address that has a known public key.
