Disable draggable link in Firefox

Anvil Q&A

What’s the link component adding here?
It might be easiest just to remove the link component and put those features back in rather than to remove the dragging.

Here’s a few others flags you could try

 {
	-webkit-user-drag: none;
	-khtml-user-drag: none;
	-moz-user-drag: none;
	-o-user-drag: none;
	user-drag: none;
}

Have you tried draggable=false?
