Thanks for filing! At first glance, this seems to be an issue with how we're simulating touch events. You can also click the hand icon to enable touch simulation (step 5 of selecting a mobile device is the same, since it enables touch by default). If you use a touch event test page like https://mozilla.github.io/mozhacks/touch-events/event-listener.html, you can see the events that we're currently sending through: touchstart touchend mousedown mouseup click Checking in the Chrome Canary 57 responsive mode, they also send essentially the same events (with some pointer versions added), but the issue doesn't appear there. However, the control UI for <video> is implemented by the browser, so it makes sense for this issue to be Firefox specific. It seems like the core issue is that videocontrols.xml uses a system group click listener, so it receives a click event even though the simulator has already called `stopImmediatePropagation`. Maybe this would be fixed by also using system group listeners in the simulator too...?
