New Article: Firefox about:config privacy and security settings
Below are some configuration settings you may consider enabling in Mozilla Firefox in about:config for privacy and security reasons. This list is not meant to be exhaustive and generally does not list entries that can easily be set via the options or preferences menu. Some of these settings have a negative performance impact or remove functionality. Also keep in mind that the further you take your Firefox configuration away from the norm, the rarer your Firefox setup might become and therefore ironically enough, the more identifiable your system may be (see https://panopticlick.eff.org/ for details) and so we recommend reviewing the list below and setting those that make sense for your scenario.
