| description | Use this skill when the user needs to manage Firefox extensions declaratively — add, update, or audit version-pinned, hash-locked XPI derivations. Applies when working on browser extensions, even if the user doesn't say "firefox-addons" or "XPI". |

Pin check

Expected: sha256-YV++7tX9MN8Y1APD3BsXqLioBeKZjgFPxrT0YoD416A=
If different, update metadata.input_hash and metadata.input_rev.
Action
- Reference an extension at
pkgs.firefox-addons.<name> — available anywhere the overlay is applied.
- Install extensions via schizofox's
extraExtensions in modules/homeManagerModules/firefox.nix:41-49.
- To update all addons:
nix flake update firefox-addons.
Gotchas
- The overlay at
modules/overlays.nix:28-29 applies system-wide, but extensions only take effect when referenced in schizofox's extraExtensions list. Just adding the overlay does nothing visible.
- Standalone home-manager configs need the overlay separately at
modules/home-configurations.nix:20.
