mozilla/addons-linter — 🔍 Firefox Add-ons linter, written in JavaScript.

Description and use

**Brief Summary (2‑3 sentences)**
Mozilla’s **addons‑linter** is a JavaScript‑based linter that validates Firefox add‑ons against the latest AMO policies and best‑practice guidelines. It helps engineers catch packaging, manifest, and API‑usage errors early, reducing manual review time and improving CI feedback quality. With a modest star count and recent activity, it is a practical tool for internal prototype pipelines and can be expanded to production with a small proof‑of‑concept rollout.

**Value**

• **Time savings:** Automates the repetitive checks that reviewers perform on every submission, cutting down on back‑and‑forth communication.
• **Consistency:** Enforces a single source of truth for linting rules, ensuring every developer receives the same feedback.
• **CI integration:** Generates machine‑readable reports that can fail builds, giving developers immediate, actionable results.

**Practical Adoption Path**

1. **Proof of concept:** Clone the repo, run the linter locally on a few existing add‑ons, and verify that the output aligns with your team’s review standards.
2. **README/Docs check:** Confirm the documentation covers the version of the Firefox Add‑on SDK you use; update any missing steps for your environment.
3. **CI hook:** Add a step to your CI pipeline (e.g., GitHub Actions, Jenkins) that runs addons-linter on PRs and fails the job on lint errors.
4. **Gradual rollout:** Enable the lint step for a single team or a subset of repositories, collect feedback, and iterate on rule configuration.

**Production Readiness**

• **Current maturity:** Medium. The project is actively maintained (last commit 2026‑05‑11) and has a modest community (≈350 ★, 150 forks), making it suitable for internal prototypes and early‑stage production.
• **Dependencies & maintenance:** Verify the transitive JavaScript dependencies for known vulnerabilities and confirm that a maintainer is responsive to security issues.
• **Risk considerations:** No major licensing or metadata concerns, but a final security audit and a check on long‑term maintainer commitment are advisable before scaling to mission‑critical pipelines.

Overall, **addons‑linter** offers a clear productivity boost for Firefox add‑on development, and with a controlled proof‑of‑concept and due‑diligence on security/maintenance, it can be safely promoted to production use.
