Wondering how to get it to work!! Rated 2 out of 5 stars

I am wondering how to get it to work. I have installed it and restarted the browser, but still can not get it to work. If someone could help me with this, then I will change my rating.

This review is for a previous version of the add-on (0.3.0). 

Icon isn't on toolbar automatically

Sorry, I haven't worked out how to make the icon appear on the toolbar during installation yet, all you need to do is 'customize' your toolbar (View | Toolbars | Customize) and drag the mobile barcoder icon (a square 'target') to your toolbar.

Sorry for the inconvenience.
