Librewolf

LibreWolf is a web browser and fork of Firefox with an emphasis on privacy and security. It is a custom and independent version of Firefox that aims to increase protection against tracking and fingerprinting techniques, while also removing all the telemetry, data collection and annoyances.

Installation

To install LibreWolf system wide add the following line to your system configuration

❄︎ /etc/nixos/configuration.nix

environment.systemPackages = [ pkgs.librewolf ];

Configuration

It is possible to configure certain presets of LibreWolf using the Home Manager module.

≡︎ 

home-manager.users.myuser = {
  programs.librewolf = {
    enable = true;
    settings = {
      "webgl.disabled" = false;
      "privacy.resistFingerprinting" = false;
      "privacy.clearOnShutdown.history" = false;
      "privacy.clearOnShutdown.cookies" = false;
      "network.cookie.lifetimePolicy" = 0;
    };
    policies = {
      ExtensionSettings = {
        "uBlock0@raymondhill.net" = {
          install_url = "https://addons.mozilla.org/firefox/downloads/latest/ublock-origin/latest.xpi";
          installation_mode = "force_installed";
      };
        "{73a6fe31-595d-460b-a920-fcc0f8843232}" = {
          install_url = "https://addons.mozilla.org/firefox/downloads/latest/noscript/latest.xpi";
          installation_mode = "force_installed";
      };
    };
  };
};

This example configures LibreWolf to enable WebGL, disable resistFingerprinting and install uBlock Origin and Noscript.
