Chrome Web Store

Chrome Web Store

Chrome extensions and themes — rating, weekly users, the developer's contact details, and the extension's real manifest permissions, which the store page itself never shows.

One extension's full store record — rating, weekly users, developer contact, version, size, supported languages, screenshots, and the manifest permissions it actually requests.
