QR Code Scanner

About

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.
