title: How to remove warning message in Chrome when uploading a directory
body: <p>When uploading a directory using <code>webkitdirectory</code> in Chrome, there is an ugly warning message that appears.  The message reads: "Upload [number of files] files to this site? This will upload all files from [directory name]. Only do this if you trust the site."</p>
  
  <p>This started just recently in Chrome version 66.0.3359.139.  </p>
  
  <p>Is there a way to prevent this warning message from appearing or to at least prevent it appearing over and over for every upload to the same site? </p>
