What is JavaScript QR Code?

"JavaScript QR Code" is a Javascript mini library made into a Firefox add-on that enables the generation of QR code images. Users can specify their preferences for dimensions and content to be encoded which could range from free text, URLs, phone numbers, to SMS. Apart from setting a container for the QR code, users also have the ability to save the QR code image, get its HTML code for use in web pages, and share the QR code via email. A standout feature of this add-on allows for QR code generation even when offline.
