User Agent: Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/57.0.2987.133 Safari/537.36 Steps to reproduce: 1- access to the following url: http://createcharts.esy.es/window-store.html 2- click the button 3- the store window opens indefinitely: if I try to close it, it reopens. If you press CTR + ALT + DEL the task window disappears immediately. It is extremely difficult to get out of this situation. Tested on Firefox 52.0.2 (32-bit) and Windows 8.1 Pro

Thanks for the test case. This also crashes with a stack overflow: https://crash-stats.mozilla.com/report/index/722b2088-44e3-425e-8d45-529621170505 The issue is that we allow other protocol handler calls to occur while Windows is spinning an inner event loop, waiting for the external application to be launched. Setting "network.protocol-handler.warn-external.ms-windows-store" to true doesn't really help, as we start displaying a modal dialog repeatedly instead. We should probably just enqueue the requests one after the other, preventing recursion.
