Prevent default `tap` not working in Firefox with touch

[jacobbuck]

The behaviour happening on Android, or when "Simulate touch events" is enabled.

Basically fingers prevents tap events in the native touchend event, which should avoid synthesizing a click event. It seems that Firefox is not behaving that way, not complying with other browsers behavior. I won't be able to fix this because the current implementation of finger does not allow me to prevent any behavior in the touchstart event using e.preventDefault().

But, there is a workaround, you could use the global preventDefault option which prevents default behavior in the touchstart native event:

$.Finger.preventDefault = true;
$('a').on('tap', function() {
  console.log("every finger's event prevents default behavior");
});
