How to refresh page After Focus in ecosia?

Is there a way to refresh the page after focus in ecosia?

This code works fine on chrome and webkit:

var blurred = false;
window.onblur = function() { blurred = true; };
window.onfocus = function() { blurred && (location.reload()); };

But does not trigger refresh in ecosia. Do you have any ideas to achieve the same result in ecosia browser?
