nimbus-prefs
nimbus-prefs is an Other agent platforms skill for AI agents, published by mozilla-firefox in the firefox repository on GitHub. Skillspace rates nimbus-prefs D (57/100) and it passed the safety scan; the rating is based on static analysis only.
Use this skill when a Firefox preference has to be remotely controllable: putting a new feature behind a pref so it can be experimented on, rolled out gradually, or disabled remotely via Nimbus. Covers declaring prefs (StaticPrefList.yaml, firefox.js), adding a feature to toolkit/components/nimbus/FeatureManifest.yaml, choosing between `fallbackPref` and `setPref`, reading values from JS and C++, recording exposure events, and pairing the pref with Glean telemetry. Trigger on "put this behind a pref", "make this Nimbus-controllable", "add a feature gate", "run an experiment on this", "setPref vs fallbackPref".
