allow sending mails only when HTML-specific things are actually done remove anything regarding "debloat" (Thunderbird news are not bloat...) enable accessibility resume from crash show condensed address only when in addressbook (this is no spam risk, and TB has GUI configs for that) collect addresses of people you write. Mail is not anonymous and stores data, this will make spam detection easier etc display inline images etc, this is very limited with sanitized HTML allow extracting calendar events, this is by choice via a popup enable the new tab page, makes no sense in TB |

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).
