We are creating website using wordpress. plugin is Maps Marker Pro. When we create marker with pop-up window to display information about that place, we want to put Virtual 360°panorama in that pop-up to show, so people can see how that spot looks like in 360°, we are using iframe code for that. Issue is that insted of showing that panorama firefox just shows blank space where that should be. There is sound but no visuals. we have checked in other browsers, Explorer, Opera, Chrome and Safari and it works normal everywhere, only issue is with Firefox. Here is link to that page, there is one icon on right , click on it and you will see. use any other browser to see how it should work. http://map.virtualmap.org/mjesta-i-lokacije/prijedor/ But people mostly use firefox so we need this issue fixed if possibly. Sorry if my english isnt very good
