识别和生成都挺不错的，不过有个小问题，就是img标签src使用base64的图标无法识别，不知道作者有没有什么办法去处理一下？

生成、识别、加上地址栏上的按钮，本来需要3个插件，现在用这一个就行了。

不错，满足了的我需求

Nice add-on, almost the one with code reading function. But does not read some QR codes easily readable by mobile apps. Few samples (links are temporal, please don't miss):

Will amend this rating when problem is fixed.

生成二维码速度很快，而且居然还支持识别二维码就很难得，唯一缺点是识别有点问题，黑色白底的最容易识别，其他颜色容易无法识别

Very very good, highly recommend. QR icon in url bar! Why do only a few people use it, this is a must have extension.
