I had to implement this recently. Thought of sharing what I had figured out;

To make it work in Safari, I had to set target: '_self',. Don't worry about filename in Safari. Looks like it's not supported as mentioned here; https://github.com/konklone/json/issues/56 (http://caniuse.com/#search=download)

The below code works fine for me in Mozilla, Chrome & Safari;

  var anchor = angular.element('');
  anchor.css({display: 'none'});
  angular.element(document.body).append(anchor);
  anchor.attr({
    href: 'data:attachment/csv;charset=utf-8,' + encodeURIComponent(data),
    target: '_self',
    download: 'data.csv'
  })[0].click();
  anchor.remove();
