 ### Aborting a save
 
+Note that Internet Explorer cannot abort saves, so 
+
     var filesaver = saveAs(blob, "whatever");
-	cancel_button.addEventListener("click", function() {
-        filesaver.abort();
+    cancel_button.addEventListener("click", function() {
+        if (filesaver.abort) {
+            filesaver.abort();
+        }
     }, false);
 
 This isn't that useful unless you're saving very large files (e.g. generated video).
