QR Code Scanner

Overview QR Code Scanner scans QR codes from page images/canvases and generates QR codes for any link. Everything runs locally; no data leaves the browser. How to test (no sign-in required) 1) Scan a QR code from a page - Open https://en.wikipedia.org/wiki/QR_code - Right-click any QR image -> "Scan QR code" - If the QR encodes a URL, a new tab opens; otherwise the text is copied. - Canvas QR codes are also supported. Try https://uutool.cn/qrcode/ : generate one, then right-click the canvas. 2) Generate a QR for a link - Right-click any link -> "Create QR code for this link". - An overlay shows the QR + URL with "Copy link" (shows "Copied" feedback) and "Download" (saves PNG). 3) Hover-link QR (optional) - Open the popup from the toolbar icon and toggle "Hover link QR codes" ON. - Hover any link for ~350 ms; a QR overlay appears. 4) Support button (optional) - The popup "Support" button opens a Stripe one-time payment URL in a new tab. This is a voluntary tip jar; the extension itself does not collect or transmit payment data. Testers do not need to complete any payment. Permissions used - contextMenus: register the two right-click items. - tabs: open scanned URLs / support link, and dispatch UI events to the active tab. - storage: remember the hover-link toggle and a first-use prompt flag (chrome.storage.local only). - host_permissions <all_urls>: users right-click QR codes / links on arbitrary websites; the content script reads pixels of the targeted image or canvas for local decoding via jsQR. No page content is sent off-device. Privacy - All scanning and generation run fully locally (jsQR + qrcode libraries). - The extension collects no user data, browsing history, or analytics. - The only outbound request occurs when the user explicitly clicks "Support", which opens a public Stripe checkout URL in a new tab.
