part of .pdf doesn't show text when opened in firefox but does show when downloaded to the desktop

when I open this link within firefox the chart (page 3 on) doesn't open. When I download the .pdf to my desktop all the information is filled in.

i noticed on my laptop, where the entire contents of the .pdf is viewable, within Firefox - under Firefox / Tools / Options / Applications / there is an app called JPS file whereas on the desktop this app does not appear
