Thunderbird
Addons
I want to write a simple addon that tags a message if there are custom headers present so that I cab have the server add tags based on various criteria.

Fixing date format
In some versions the date format gets stuck on US no matter what your locale or preference is. One way I've found to force it to the correct format is to create a shell script to set LC_TIME before launching, e.g.
#/bin/sh
export LC_TIME=en_GB.UTF-8
/usr/bin/thunderbird
Remember to chmod +x your script, and you may also need to enable en_GB.UTF-8 by running dpkg-reconfigure locales if you don't already have that locale set. Once all that's done, change the launcher command in /usr/share/applications/thunderbird.desktop to your new script.
PGP privacy problems with Thunderbird
Since around version 78 of Thunderbird, they've changed the way GnuPG is integrated with. Now all the key info including private key access passwords are imported and stored in Thunderbirds own file structure. To ensure your private keys and their access passwords are secure, you must set a "master" or "primary" password in the security & privacy settings. See this article for more details.
