Does this skill support Manifest V2?

No, this skill is specifically optimized for Manifest V3 to ensure compliance with modern Chrome Web Store requirements and performance standards.

Can I use this for Firefox extension development?

While Chrome and Firefox share the WebExtensions API, this skill is primarily tailored for the Chrome-specific Manifest V3 implementation. It may work for Firefox but is not its primary focus.

Does it include security best practices?

Yes, it enforces the use of safe DOM APIs, discourages eval() and innerHTML, and follows the principle of least privilege for extension permissions.

How does this skill handle background tasks?

It implements Manifest V3 Service Workers. Since these are ephemeral, the skill provides patterns for using chrome.alarms for persistence and state management.
