Currently using react-dnd-html5-backend version 2.1.2 and when I attempt to drag plain text i get the following error in the console:

After some searching the only reference to this problem I have seen is from this stackoverflow answer.

I'm running into this issue as well. Only Firefox users, including the latest version 60.
