## user.js | Firefox, Firefox ESR and Firefox Nightly.
A `user.js` file for configuring and hardening Desktop 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, one connection could not be blocked anymore:

* firefox.settings.services.mozilla.com

https://support.mozilla.org/en-US/kb/how-stop-firefox-making-automatic-connections (last section)

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

## Adding new search engines

Installing new search engines from mycroftproject.com web is not working. Besides, they have embedded Google analytic trackers recently.
