title: Firefox, developer tools and file download in separate (temporary) tab
body: <p>I have a website that do xhr that will result in file download. FF open new tabl for that filedownload, and XHR request will not be shown on network tab on original page.</p>
  
  <p>How can I get request info for that xhr (best if I could get file download as response, so that I get both request and response info)?</p>
