There are a few scams that pretend to be qr scanners on this Firefox addons page, but this one works, so, not a scam.

A Simple, No-Frills QR Code Reader

I recently discovered a great little Firefox add-on called QRCode Scanner. It's super easy to use and does exactly what it's supposed to: scan QR codes.

Here's the best part: No need for extra icons or toolbar clutter. Just right-click on a QR code image and select "Decode QR" from the menu. Boom! You've got your result.

It's simple, it works, and it's perfect for those who just want a quick and easy way to scan QR codes. If you're like me and don't need a fancy QR code reader, give this one a try.

light extension, reads QR code well. They must be enabled after installation in the extension options

Nice.

For popup windows you do not need "Access your data for all websites"

Does not scan local file image when I open the image in a new tab

掃不出QR Code剪裁示別功能形同虛設

部分二维码需要在线识别，整体来说体验不错，效果挺好

Right click QR, decode, grab data, profit. Easy to use, thanks!

至少能用，以前我是用别的二维码扫描器，更新系统后就不能用了

非常好，直接右键点击浏览器中的图片，选择识别就可以了
