Problem to save QR code Rated 2 out of 5 stars

I installed this addon but I don't know how to save the QR code generated.
If I use the small square on the bottom right of the browser, the QR code appears but I have no way to save it. Same thing if I use the right click button "Create bar code from link". I'm using Firefox 3.6.17.

How do you do?

Thanks.
