PassB on NixOS

Prerequisites

• you should be on a version of nixpkgs that has this comit
• you still need to download the passB browser addon from mozilla: https://addons.mozilla.org/en-US/firefox/addon/passb/

Preparations

run ./generate.shell

install with an overlay

• symlink the passb-overlay.nix into the folder ~/.config/nixpkgs/overlays
• this overrides your firefox-package, so just call nix-env -iA nixpkgs.firefox

without overlay, from your ~/.config/nixpkgs/config.nix

# ~/.config/nixpkgs/config.nix
{
  packageOverrides = pkgs: with pkgs; {
    all = pkgs.buildEnv {
      # ... your other packages
      (firefox.override {  extraNativeMessagingHosts = [ (import ./passB/default.nix { inherit pkgs; }).firefox-hostApp ]; })
    }
  };
}
