XPC errors don't e from calling a pure Javascript method like parseInt (and the radix argument is optional by specification, so all those ments are wrong on many counts).

You are missing the third useCapture argument on all your addEventListener calls:

Here:

document.body.addEventListener('touchstart', function(e) {
    ...
}, false);  //<-- add third argument

Here:

content.addEventListener('transitionEnd', removeTransition, false);  //<-- add third argument

Here:

document.body.addEventListener('touchend', function(e) {
    ...
}, false);  //<-- add third argument

Here:

content.addEventListener('transitionEnd', removeTransition, false);  //<-- add third argument

And here:

document.body.addEventListener('touchmove', function(e) {
    ...
}, false); //<-- add third argument

Note that in a newer specification, the argument has been made optional. But that doesn't really matter.
