Thunderbird User.JS

Thunderbird privacy, security and anti-fingerprinting: a comprehensive user.js template for configuration and hardening

🟪 user.js

An user.js is a configuration file that can control hundreds of Thunderbird settings.
For a more technical breakdown and explanation, you can read more on the overview Wiki page.

🟩 Thunderbird user.js

The thunderbird user.js is a template which aims to provide as much privacy and enhanced security as possible, and to reduce tracking and fingerprinting as much as possible - while minimizing any loss of functionality and breakage (but it will happen).

Everyone, experts included, should at least read the implementation wiki page.

It differs from the arkenfox user.js in that the focus is to keep Thunderbird as an e-mail client and disable as many web browsing features as possible. We believe web browsing should be done in a web browser, and not an email client.

If you're using Thunderbird (< 68) with Tor we suggest that you install the TorBirdy add-on. If you are using Tor, you should also consider using Tails or Whonix.
If you're using Gmail, please check this article about OAuth2.
For information about extensions, see the Wiki.
Calendar users should see this page.

Also be aware that this user.js is made specifically for Thunderbird and has only been tested in the latest stable release.
