User Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:49.0) Gecko/20100101 Firefox/49.0 Build ID: 20161019084923 Steps to reproduce: 1. Go to this demo: http://axel.ihrdc.com/steven/IPIMSDemos/flash-in-slideshow.html 2. Go to one of the next two slides and press play, click again to pause, and click again to play 3. Right click on the Flash video to bring up the context menu Actual results: It's difficult to play or pause the Flash videos on the 2nd and 3rd slide as it usually takes many clicks before one of them registers. Also I noticed that if you right click on the Flash item the context menu appears in the wrong location way to the right. These issues don't appear on the first slide. I believe these issues are caused by the transform: translate CSS property as that's the property that moves the slides. Expected results: The slides should all behave similarly to the first slide with clicks registering correctly and, although less importantly, context menu displaying correctly.
Just a note
Just a note that this is not an issue on Chrome, IE, or Opera.

smaug, do we/should we be translating the coordinates of mouse events as delivered to a plugin when it is transformed?
no idea. This is more a plugin handling related question. I have no idea what Flash expects.
