Extensions patterns for Manifest V3
summary
Manifest V3 moves host permissions from install-time grants to runtime choice, encouraging a runtime permission model that uses activeTab for temporary access and prompts (example: an Inverter extension switches from global content scripts to inject-on-click). Chrome ships Declarative Net Request (Chrome 84) to block/modify requests without site data, plans Dynamic Content Script APIs, and targets Chrome 88 for MV3 stable with the Web Store accepting MV3 uploads in Jan 2021. Practical patterns: contextual prompts, post-install onboarding, and permissions API requests.
