Modern Chrome Extension Development: Manifest V3 Architecture & Best Practices

Question

Hey devs! I put together a practical guide covering the fundamentals of building Chrome extensions with Manifest V3.

Core highlights:

Transitioning from persistent background pages to event-driven service workers

Two-way communication across popups, background workers, and injected content scripts

Safe storage persistence and permission management for smooth store approval
