Answer 1

I'm not sure exactly what causes this, but part of the problem is probably that after the clone, you have two #f1's. It might work better to define the filter in a single <svg> that you never clone, and have the cloned <svg> just reference that.

<svg xmlns="http://www.w3.org/2000/svg" version="1.1" height=0px width=0px id="defs">
  <defs>
    <filter id="f1" x="0" y="0">
      <feGaussianBlur in="SourceGraphic" stdDeviation="15" />
    </filter>
  </defs>
</svg>
<svg xmlns="http://www.w3.org/2000/svg" version="1.1" height=100px width=100px id="rect">
  <rect width="90" height="90" stroke="green" stroke-width="3"
  fill="yellow" filter="url(#f1)" />
</svg>

See this update fiddle.

You need to update the ID on the <filter> and update the filter on the rect.

window.makeClone = function (){    
    var cloneSVG = $('svg').clone(true);
    cloneSVG
        .find("filter")
            .attr("id", "f" + n)
            .end()
        .find("rect")
            .attr("filter", "url(#f" + n + ")")
            .end()
        .appendTo('body');
    n++;
}
window.removeClone = function (){
    $('svg:last').remove();
}
