I had the same problem. Firefox is trying to open it using Nautilus. On Mate Desktop Nautilus is not pre-installed so… Just install Nautilus and the problem is gone…
sudo apt install nautilus

@konmal88 Installing Nautilus is going to create more problems than it solves.
This is finally fixed in 17.04. It took long, I know.
