title: How can I download a file in Firefox Webextension without using chrome.downloads.download?
body: <p>in my chrome extension I use <code>chrome.downloads.download</code> to initiate a file download, but in firefox Web Extensions this method is not yet implemented (as seen <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=1245597" rel="nofollow">here</a>).</p>
  
  <p>Is there any other way I can initiate a file download from within my firefox add-on?</p>
  
  <p>Thank you</p>
