User reviews

Users find the JavaScript QR Code add-on simple, lightweight, and functional for generating QR codes from any page text or link with resizing options. However, multiple reviews expressed privacy concerns because it uses an external Google Charts API without clear disclosure, causing data to be sent externally.
