Thunderbird-hardening-automation: Automatically update secure settings for Thunderbird, configure them to your needs

Thunderbird is great, but very complex and possibly insecure and not private.

Threat model is an important key word here. Imagine you would write Mails over Tor/Tails only and need a secure Mail client.

(Btw I can recommend Carburetor Flatpak for that).

Because of this, the thunderbird hardening user.js, similar to the Arkenfox project exists.

But it is a bit too strict for most threat models. Also settings might change or break, and this has no automatic updating mechanism.

(I should upstream the updater)

The user.js is also just a template, so a ton of mostly not needed configs will stay there.

This project makes the setup of the hardening user.js easy.

Once setup, the script is placed in ~/.local/bin and a user systemd service runs it every once in a while.

You can comment out lines if you want to keep certain settings.
