User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.0; de; rv:1.9) Gecko/2008052906 Firefox/3.0 Build Identifier: I think that a nice feature for a future version of Thunderbird would be to support OpenPGP natively (without to have external programs like GnuPG installed, like the already implemented support for S/MIME). I think it's more importent than ever to offer this security features today. Because many users are often deterred by the extra installation and complicated configuration. I think a direct implementation would animate more people to use mail encryption. Reproducible: Always
