Seems to be an abandoned and now defunct project

It is a bit tricky to make it work at first. But it works 100%!!!!! Outstanding app! Thank you!

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.

The extension is always grayed out; can't even open it. Uninstalling.

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!
