I can reproduce this on Arch Linux with Firefox 63.0.1 (64-bit). I think the file is somewhat corrupt given the console logs:

Adobe Reader shows bad images and an error message on page 1.

Indeed, the image is also bad in PDF.js, which is probably explained by the Warning: decodeScan - unexpected MCU data, current marker is: 4ab line above. Thank you; marking this as a corrupt PDF file for now.
