Hi,

Thanks for the details. I was able to reproduce on Windows 10, on Firefox Nightly version 73.0a1 (2019-12-12) (64-bit) and firefox 71.0. Browser seems as if it hanged, but actually by pressing ESC the dragsession is canceled and user may proceed.

I've chosen a component so that the issue is reviewed.

Best regards, Clara.

Closing as duplicate of the later bug 1830924, since that one has more discussion.

Either way, this is fixed in the latest Nightly.
