Yep, there is penango fore firefox+gmail.

Well given that a lot of users write emails with html markup, this
really does not bother me.

Well I was referring to the following 10 years old bug

I have the feeling this is a design decision by  "philosophy":
thunderbird/semonkey don't encourage the use of self-signed certificates
(BTW I just learn that there is a add-on, key-manager which generates
self-signed certificates, similar as it seems to me to the BAT.

At first I thought that I need to use openssl in order to extract your
cert and import in under authorities 
openssl pkcs7 -in MFPA.p7 -inform DER -print_certs > out.cert

(Which would be bad, because command line openssl is not what the
average user would call, comfortable and windows users have to install
openssl a part)

However it is not necessary I just export our signature as a pem file
and import in under authorities. Still this is very uncomfortable...

BTW, I see you switched back to pgp, but why do you use old inline mode
and not pgpmine?
