empty subject replacement to reduce metadata
OpenPGP addon for Mozilla Thunderbird
Brought to you by:

A cool feature would be to replace an empty subject line with the (decrypted) first line of the message in Thunderbird. That way we can reduce Meta data (the mail subject).
I think we should do this unconditionally for PGP/MIME messages as suggested here: http://lists.gnupg.org/pipermail/gnupg-devel/2015-January/029382.html
working on it
The functionality has been implemented as discussed on the gnupg-devel mailing list and according to the drafts specification here: https://github.com/ModernPGP/memoryhole
The feature is currently disabled by default for sending messages, and will be enabled as default in the version after the next version (i.e. to have a broad basis of users to have mail clients that support the feature).
