Building a Chrome extension with Manifest V3 involves setting up the manifest file, writing service workers for background tasks, and injecting content scripts for webpage manipulation. This framework enables custom browser tooling and automation.

Service workers in Manifest V3 manage background logic and Chrome API events without DOM access, whereas content scripts execute within the context of a webpage to read and modify its DOM elements dynamically.

Yes, you can use JavaScript to build popup UIs for Edge extensions. The Manifest V3 framework supports popup development to handle user interaction, enabling custom interfaces that leverage Chrome APIs across compatible browsers.

Manifest V3 is the current standard required for developing browser extensions that automate web pages. It provides the service worker and content script architecture necessary to execute dynamic browser interactions and custom automation tasks.

To integrate Chrome APIs in a Manifest V3 extension, declare the required permissions in your manifest file and invoke the APIs within service workers or popup UIs. This enables enhanced functionalities like custom browser automation and tooling.

Service workers in Manifest V3 are non-persistent and event-driven, terminating when idle to save memory. This requires extension developers to manage background state carefully, unlike older persistent background page architectures.
