IE, in classic fashion, requires you to use a proprietary method for "saving" a blob.

msSaveBlob or msSaveOrOpenBlob is what you're looking for.

Instead of adding it as the href, add an onclick handler to your a tag and call navigator.msSaveBlob(blob, "Sample Name");

Additionally if you need to support other browsers you'll need some other code to support those browsers.

For example:

var content = new Blob(["Hello world!"], { type: 'text/plain' });
var btn = document.getElementById('btn');

if (navigator.msSaveBlob) {
  btn.onclick = download;
} else {
  btn.href = URL.createObjectURL(content);
  btn.download = true;
}

function download() {
  if (navigator.msSaveBlob) {
    navigator.msSaveBlob(content, "sample.txt");
  }
}

Download the text!
