user.js | Firefox, Firefox ESR and Firefox Nightly.

This a is a fork of the arkenfox project.

The user.js file is for configuring and hardening Firefox privacy.-

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'll have to add them to the host list of your OS.

Adding new search engines

Installing new seach engines from mycroftproject.com is not working anymore. Follow this guide instead:
