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 Thunderbird settings - for a more technical breakdown and explanation, you can read more in the wiki.
🟩 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 wiki, as it contains important information regarding a few user.js settings.
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 is only being tested against releases with extended support (ESR).
