Go to bug url, and click on Maps and Directions. The resulting map doesn't work (appears to be powered by microsoft). Works fine in latest Firefox. Tested with r29807. There are a couple of javascript errors: TypeError: Null value http://dev.virtualearth.net/mapcontrol/mapcontrol.ashx?v=4 Value undefined (result of expression VENetwork.GetExecutionID) is not object. http://dev.virtualearth.net/mapcontrol/mapcontrol.ashx?v=4 Not sure if this is related at all to bug 6519
The site works with User Agent set to Firefox. Evangelism bug.
