Firefox Desktop is indeed the web browser on PC.

It sounds to me like you can definitely use fxpay to bill to credit cards on desktop. I'm not sure about the cell phone bill thing, though.

Actually you can [theoretically] put a charge on your phone bill from desktop but there are some open bugs around this and it's not a high priority use case for us. The main case for desktop is credit card processing.
