Dragging a File from File Explorer Causes Google Chrome to Crash

Hey everyone,

A team member found an interesting bug today that caused chrome to go non-responsive. The cause was simply dragging a file from the file explorer onto a drag and drop upload area. It is reproducible on every site I’ve tested, including Gmail and Dropbox.


  • Go to https://mail.google.com
  • Click compose
  • Click attach files (close any of the annoying popups that appear)
  • DRAG a number of files from the file selector window to the new message screen (they will start to upload) (IMPORTANT: these need to be dragged from the file selector popup, NOT a new explorer window)
  • While they are still uploading hit cancel on the file browser window. Browser will go non-responsive
