title: How to get Mozilla Firefox to show file download progress
body: <p>My MVC application has a simple file download controller action that downloads a file.</p>
  
  <p>Here is the code:</p>
  
  <pre><code>public ActionResult Download(string fileId, string filename)
  {
      //var fullFilePath = FileService.GetFullPath(fileId); // get the path to file
      var fullFilePath = fileId;
      return File(fullFilePath, "application/octet-stream", filename);
  }
  </code></pre>
  
  <p>I can download/save files successfully but can't seem to get Firefox to show the file download progress. All other browsers shows the file download progress.</p>
  
  <p>Does anyone know how to get Mozilla Firefox to show the file download progress?</p>
