User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:16.0) Gecko/16.0 Firefox/16.0 Build ID: 20120713030548 Steps to reproduce: I visited Bing Maps. Actual results: In the mapping area, the user interface (zoom buttons, copyright information and a brown bar at the top with options for switching between map and satellite imagery) is not displayed. Also, when zooming in, instead of the image expanding smoothly, the current view shifts to the bottom right corner of the screen until the new images load.
