Thunderbird User.JS

An ongoing comprehensive user.js template for configuring and hardening Thunderbird privacy, security and anti-fingerprinting

🔷 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. It differs from the ghacks user.js in that the focus is to keep Thunderbird as an email 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 with Tor we suggest that you install the TorBirdy addon. If you are using Tor, you should also consider using Tails or Whonix.
• If you're a Gmail user see 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.
