常见问题

What is Manifest V3?+

Manifest V3 (MV3) is the new architecture framework for Chrome extensions, heavily restricting background scripts in favor of Service Workers to improve security, privacy, and browser performance. Google Web Store has officially sunset MV2 extensions.

Do I need all permissions?+

No, in fact you should request as few permissions as absolute necessary. Broad permissions (like `<all_urls>`) drastically increase the manual review time required by the Google Chrome Web Store review team.
