QR Radar - Real-Time Screen QR Scanner 作者： Radetski

QR Radar is an ultra-fast, privacy-first Firefox extension that recognizes QR codes anywhere on your screen in real-time using WebAssembly and hardware acceleration.

• Real-Time HUD Overlay: Tracks QR codes with smooth bounding boxes and floating action cards directly on web pages and full-screen video players (YouTube, Vimeo, streams).
• Instant Actions: One-click copy or open detected URLs, Wi-Fi networks, emails, phone numbers, and geo-locations.
• 100% On-Device & Private: All recognition runs locally via WebAssembly (ZXing-C++). Screen data never leaves your computer.
• Ultra-Low CPU Usage: Off-thread WebAssembly worker with adaptive idle sleep prevents tab lag and battery drain.
• Customizable: 5 HUD neon color themes, adjustable scan rate (up to 30 FPS), sound effects, and domain exclusions.
• Quick Keyboard Shortcut: Press Alt+Q anytime to toggle the scanner on or off.

QR Radar does not collect, store, or transmit any personal data, screen captures, browsing history, or analytics. Everything stays strictly in your browser.
