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