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

### :purple_square: 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](https://github.com/HorlogeSkynet/thunderbird-user.js/wiki/1.1-Overview) Wiki page.

The `thunderbird user.js` is a **template** which aims to provide as much privacy and enhanced security as possible.  
It differs from the `arkenfox 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 (< 68) with Tor we suggest that you install the [TorBirdy](https://addons.thunderbird.net/addon/torbirdy) add-on. If you are using Tor, you should also consider using [Tails](https://tails.boum.org/) or [Whonix](https://www.whonix.org/).
- If you're using **Gmail**, please check [this article about OAuth2](https://github.com/HorlogeSkynet/thunderbird-user.js/wiki/3.1-OAuth2-Users).
- For information about [extensions](https://github.com/HorlogeSkynet/thunderbird-user.js/wiki/4.1-Extensions), see the Wiki.
- **Calendar** users should [see this page](https://github.com/HorlogeSkynet/thunderbird-user.js/wiki/4.1.1-Calendar).

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