походу единствненое норм, которое и сканирует QR-коды тоже.

Scanning qr code in a web page works very well! Great addon!

I really like being able to get the QR from the web page without having to screenshot or anything. Makes getting links out of fliers sent over email much easier. It just works!

我用过的最好的二维码扫描工具

Scan QR Code with the camera is the best feature!

非常好用，没有广告，简洁全面

Útil y fácil de utilizar.

您伟大的作品值得一个推荐标签；优雅，并且强悍

scan region (read from QR on screen) feature is good

perfect ,simple ,easy ,beautiful

Simple, lightweight, and does what it says

Funktioniert direkt :)

Does everything well: links, images, even images with hyperlinks and you can easily edit the content before saving. The region selection requires using the context menu twice, which is a bit weird to get used.

Doesn't work in PDF/SVG viewer mode or any internal "about:" pages, but it's probably a limitation of the API.
edit: Link and picture scan revert to default tab mode when used in a private window.
