A comprehensive list of Firefox privacy and security settings

[Batu69]

Mozilla Firefox is without doubt the web browser that gives the most control to users in regards to privacy and security. Firefox users find some of those options listed in the graphical user interface, but full control over the browser is only granted if changes are made to the browser's configuration.

This can be done on the about:config page, or by placing a user.js file in the profile directory of the Firefox user.

The following list is a work in progress. Firefox is updated regularly and preferences may change because of this. There may be new features and new preferences as well, and the idea of this guide is to get a discussion going that improves this list on a continuous basis.

I'd like to thank Ghacks' reader Pants for creating the initial list and giving me permission to publish it here on the site.

Note: If you prefer to use about:config to manipulate those entries, check out our overview of Firefox privacy and security about:config settings which lists all preferences and values you can set them to.
