Simple and functional Rated 5 out of 5 stars

The extension is simple but functional. Just right-click on a link or a text selection, choose to convert the link or selection into a QR code and the code immediately appears on your screen.

Pros:
- simple and intuitive handling
- uses a high error correction level (H)
- does not generate redirect links and does not encode any other information except the selected link/text
- does not request any service for generating the QR code (tested via wireshark) => keeps privacy of the user

Cons:
- QR code cannot be generated for URLs located in the address field

Edit:
- no cons anymore in new version :-)

This review is for a previous version of the add-on (0.5.2). 

"QR code cannot be generated for URLs located in the address field" - Now you (finally!) can ;)
