It smacks of being a fault in Firefox.  If I download the file on
Linux, I can then read it using Adobe Reader 9 or evince 3.18.2, but
still not with Firefox 53.0.  Of course, it's possible that there's a
fault in the file that doesn't affect other readers - Adobe Reader has
had a spate of problems with embedded fonts, but it may have been the
PDF generators that were at fault in that case.

The short-term practical solution is to change the plug-in action for
PDF's - short URL is about:preferences#applications.

like an old or recurring problem with Firefox.
