firefox-config

Firefox Nightly + Textfox + fx-autoconfig eigenhome module.

Standalone flake that bundles Firefox Nightly, Textfox theming, fx-autoconfig (userChromeJS), NUR extensions, and tridactyl into a single eigenhome home module.

Integration

NixOS flake input

In ~/.config/nixos/flake.nix:

firefox-config = {
  url = "path:/home/eigenmage/dev/projects/firefox-config";
  inputs.nixpkgs.follows = "nixpkgs";
  inputs.eigenhome.follows = "eigenhome";
  inputs.home-manager.follows = "home-manager";
  inputs.nur.follows = "nur";
  inputs.nix-firefox-addons.follows = "nix-firefox-addons";
};

Overlay

The nix-firefox-addons overlay is re-exported and applied in the NixOS config's overlay list:

firefox-config.overlays.nix-firefox-addons

This makes pkgs.nur.repos.rycee.firefox-addons available system-wide.

Home module

The primary integration is a single line in the gaiagear eigenhome extraModules:

firefox-config.homeModules.firefox

This loads modules/firefox.nix with all dependencies pre-wired — no additional configuration needed in the NixOS config.

HM compatibility

The flake constructs its own wrapHmModule from eigenhome's HM compat layer:

wrapHmModule = import "${eigenhome}/modules/hm-compat/wrap-hm-module.nix" { inherit hmExtLib; };

This is passed into the module as a special arg, so firefox-config wraps its internal HM module usage independently — the consuming flake doesn't need to handle HM wrapping for Firefox.

programs.firefox.package = null

The module sets programs.firefox.package = null to bypass Home Manager's .override wrapping, which is incompatible with fx-autoconfig's custom Firefox wrapper. The Firefox package is added to packages directly instead.

Flake inputs

Input	Purpose
eigenhome	Home management framework + HM compat
home-manager	HM module source (wrapped, not used directly)
textfox	Minimal Firefox CSS theme
firefox (flake-firefox-nightly)	Firefox Nightly binary
nur	Nix User Repository
nix-firefox-addons	Declarative Firefox extension packaging
fx-autoconfig	userChromeJS loader (non-flake)
firefox-scripts	userChromeJS scripts collection (non-flake)
