Summary
This one gets straight to Manifest V3 patterns and the specific things that break extensions in production. It covers the entire lifecycle from building to Chrome Web Store publishing, with mandatory rules that address the most common footguns: sandboxed iframe execution, service worker ephemerality, side panel triggers that developers constantly forget, and the silent undefined returns when you miss the tabs permission. The context menu feedback guidance is solid advice, and the chrome.identity OAuth workflow with the key field is something you'll actually need when integrating sign-in. Written for people who want working extensions without debugging CSP violations at 2am.
