Browser Extension Builder

Covers the full stack of building browser extensions from manifest setup to Chrome Web Store publishing. You get practical patterns for Manifest V3 architecture, content scripts that inject UI into pages, service worker communication, and chrome.storage usage. The monetization section is refreshingly honest about Chrome killing built-in payments, so you'll need your own backend for freemium models. Includes validation checks for common mistakes like excessive permissions and deprecated V2 manifests. Best for shipping actual extensions people use daily, not toy projects. The architecture templates and communication patterns save you from fighting extension security constraints.
