Sencilla y necesaria, sin más. Sólo lo que es para un QR: la exhibición y la creación.

Love it. No permissions, no bloat. Just an icon in the URL bar.

Very useful to have.

Works perfectly

This should come as a default feature for Firefox. Very good and simple extension.

It does exactly what I need: converts the current URL to a QR code and also allows to change the text to anything. I use this addon to type my SMS/other messages on the large keyboard and scan them into my phone. I love it.

手机扫网页链接一点即用，偶尔需要用文本生成时也很方便快捷。界面整合至地址栏，小巧简约，将最常用的核心功能以最少的操作量实现，非常符合我的审美！

Nice, simple and no adds. Love it

It's good and helpful

Simple add-on without unnecessary permissions. The address bar location is ideal.

Simple add-on that works great. It generate instant qr code and even allows you to download qr in PNG or svg. Great work.

I wish it was integrated into the browser directly but this one does the job. Love the placement of the button in the address bar

No-nonsense extension. And best of all: no permissions needed. Strongly recommended.
