Do you know why this is? 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. >From the support page at https://support.mozilla.org/en-US/kb/view-pdf-files-firefox , it looks like an old or recurring problem with Firefox.
