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 project.
Goals
- enhance privacy and security
- 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

How to stop Firefox from making automatic connections Section "Automatic updates and Security/Login breach information"
So you will have to include it to the host list of your OS.
Nevertheless, if you are on a .deb GNU/Linux distro consider installing Abrowser from Trisquel. It lacks that connection:
Or if you are a Windows user have a look at these Unofficial Icecat builds:
If you are still interested in using firefox vanilla take into account it makes a connection to aus5.mozilla.org in order to autoupdate itself so you'll also have to add it to your host list.
Alternatively, you could copy the folder distribution with the policies file into your firefox installation folder. More information about this:
