react-dnd: Drag and drop not working in Firefox

I can’t drag elements when using Firefox in my app. I’ve tried with the chess example and seems not to be working either.

First time you try to drag, the dragged element seems to loose opacity (like when it’s being dragged) but it doesn’t move. Then you try again and the console shows the error:

Error: Cannot call beginDrag while dragging

Using Firefox v53.0.3 (64 bits) in macOS 10.12.5

I am running into this problem as well on the FF 54.0 both in the demo page and also using these versions locally:

"react-dnd": "2.4.0",
"react-dnd-html5-backend": "2.4.1",

I have narrowed down the problem to HTML5Backend.js. The “dragenter” event is not being called for some reason.

Edit: it seems to be working again all of a sudden on FF. Not sure why.

Edit: nvm, turns out the newer FF works.

I think I have this problem - it works on 54.0b8, but DnD can hang on 54.0a2 (Developer Edition).
