DFD refers to the Data Flow Diagram. It is used by software engineers who design the systems. It can be used for visualization or data processing. It isn't something you need to be concerned with for use of your browser. A programmer may refer to it in the event there are problems. If an error message came up regarding it, usually it will ask if you want to send a report. Simply click send it to the designers and they can usually fix it in the next update they send out.
Hope that helps!
