## user.js | Firefox, Firefox ESR and Firefox Nightly.
A `user.js` file for configuring and hardening Firefox privacy.

Concretely, this is a fork from the [arkenfox](https://github.com/arkenfox/user.js) project:


## Goals

* enhance privacy
* improve performance
* better fingerprint possible
* reduce automatic connections to the minimum posible

## Considerations

This user.js is a fork from the arkenfox project with a substantial divergence. It tries to avoid all the automatic connections even though security could be reduced slightly.
For instance, OSCP is a privacy breach. Nevertheless, it is also a security feature. This user.js disables them as well as safebrowsing, automatic addons connections and so on. You will have to check manually addons updates in the related preferences section.

However, 2 connections could not be blocked anymore:
* firefox.settings.services.mozilla.com
* content-signature-2.cdn.mozilla.net

So you will have to include them to the host list of your OS.
