addons-linter

It's the tool used by addons.mozilla.org for submissions, ensuring checks are up-to-date with Firefox's security and policy standards, which helps extensions pass review faster.

Can be used as a standalone CLI, via a JavaScript API for custom workflows, or in CI/CD pipelines, as demonstrated in the README with configuration examples.

Uses scanners for JavaScript, HTML, and language packs with rules based on ESLint and other parsers, providing detailed error reporting with code references for debugging.

Includes a --privileged flag for linting extensions with elevated access, adjusting checks to handle specific security and policy requirements not covered in regular mode.
