Description: 32 |

The deployment of the Firefox Customization File(s) allows to extensively and holistically modify the behaviour of the Mozilla Firefox browser. The settings listed below are mainly centered on reinforcing privacy with a few touches on security, too. For a full list of available settings, please, for example, see a fairly comprehensive list of Firefox privacy and security settings managed by Martin Brinkmann.

This code is partially based on the advice "Browser Security Guidance: Mozilla Firefox" released by the UK government's National Technical Authority for Information Assurance (CESG), which is part of the Government Communications Headquarters (in UK).

    117 |

    118 |

  1. 119 |

    Step 1: Recommended configuration

    120 |

    Firefox is configured by using two configuration files (a system-wide installation):

    Build a lock file with computer wide settings (prefs.js) containing only two rows of actual data (in addition to the comments, listed below starting with "pref(") and a configuration file (firefox.cfg) containing all the many configuration settings in accordance with the settings listed further down below starting with "lockPref(". These files should contain the settings which the organisation wishes to configure and enforce. The files are then deployed to the EUDs in %programfiles(x86)%\Mozilla Firefox\firefox.cfg and %programfiles(x86)%\Mozilla Firefox\defaults\pref\prefs.js in Windows – for the file locations and file names in other platforms, please see the tables above. Please note, that a prefs.js file inside a Mozilla Firefox user profile directory (the path to a user profile directory is mentioned in the optional Step 2) shouldn't be altered, since that file with the same name (which resides inside a Mozilla Firefox user profile directory) is generated automatically by the program itself. The main difference between these files, which have a common name (prefs.js) is that the other resides inside the program installation folder (target) and the other is found under user profiles (not to be changed).

    201 |
      202 |

      prefs.js (lock file) content:

      203 |

      204 |

      205 | pref('general.config.filename', 'firefox.cfg'); 206 |
      pref('general.config.obscure_value', 0); 207 |
      208 |

      209 |
    210 |
    2. 211 |

    212 |

    213 |

  2. 214 |

    Step 2: Optional configuration (concerning a single Firefox user profile)

    215 |

    Alternatively, if a computer-wide installation is not preferred, Firefox can be configured with a single configuration file, where the installation will concern only a single Firefox user profile.

    216 |
      217 | 218 | 219 | 220 | 221 | 222 | 223 | 224 | 225 | 226 | 227 | 228 | 229 | 230 | 231 | 232 | 233 | 234 | 235 | 236 | 237 | 238 |
      N.B.Please read A brief guide to Mozilla preferences
      N.B.In this option before doing any modifications that concern an existing Firefox user profile (for instance in Windows %APPDATA%\Roaming\Mozilla\Firefox\Profiles\[a_profile_name]\), it is highly recommended to backup the whole existing Firefox user profile directory before anything is copied to or otherwise altered inside the Firefox user profile directory, since the settings listed below may alter the browser behaviour quite a bit.
      N.B.In this option it is highly recommended to create a completely new user profile to use with the custom configuration settings.
      N.B.Please note, that a prefs.js file inside a Mozilla Firefox user profile directory shouldn't be altered, since that file (which resides inside a Mozilla Firefox user profile directory) is generated automatically by the program itself.
      N.B.In this option it is mandatory to follow option 3 below.

      280 |

      281 |
    282 |

    Build a configuration file called user.js containing all the many configuration settings in accordance with the settings listed further down below starting with "lockPref(". The file should contain the settings which the organisation wishes to configure and enforce. Please notice that since lockPref() may be called only in the configuration file (firefox.cfg), and user.js can only contain pref(), user_pref() and sticky_pref() calls, it is mandatory to follow the Step 3 below before deployment. The file is then deployed to the EUDs in %APPDATA%\Roaming\Mozilla\Firefox\Profiles\[a_profile_name]\user.js in Windows – for the file locations and file names in other platforms, please see the table above. Please note, that a prefs.js file inside a Mozilla Firefox user profile directory shouldn't be altered, since that file which resides inside a Mozilla Firefox user profile directory is generated automatically by the program itself.

  3. 287 |

    Step 3: Tweaking the settings: Setting the settings settable rather than in a locked state

    288 |

    In the firefox.cfg file, if the settings are preferred to be controllable (not locked) on the about:config -page, please change every 289 |

      290 |
      lockPref(" 291 |
      292 |
      to 293 |
      294 |
      pref(" 295 |
      296 |
    297 |
    Please notice that lockPref() may be called only in the configuration file (firefox.cfg), and user.js can only contain pref(), user_pref() and sticky_pref() calls.
