User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.12; rv:57.0) Gecko/20100101 Firefox/57.0
Build ID: 20170828100127

Steps to reproduce:

Load up a fine animated GIF like

Drag it into an iMessage chat window and send it

Actual results:

It sends a static image, the first frame of the GIF

Expected results:

It should animate. Using Google Chrome drag/drop works (it animates), but copy/paste doesn't (static image, same as firefox). In Safari, both drag/drop and copy paste work (animation preserved).

This feels like a small thing but I'm sure there are other areas where Firefox drag/drop isn't behaving fully "natively" that this might be a good test-case for. Also, this is like 90% of my need for a browser—to find good GIFs and send them at people.
