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
After downloading Mozilla's add-on, the alert toolbar appeared with "Open With Different Viewer" which I clicked (sshot 1). The pop-up opened (sshot 2) I chose Open with Adobe Reader (default) - which is my default reader.
The final product after using "Open with Different Viewer" and choosing Adobe Reader (default) shows the newsletter having all its components visible. The pdf appears in a new window while the original is still open in the original window.
BTW - the adobe reader on the desktop is Adobe Reader XI.Ink
whereas the laptop is Adobe Reader X.Ink (the pdf document opens correctly via the link in the email)
This information may help Mozilla identify and do code modification to address the .pdf issue.
I go to this website regularly and have not had any issues with it or my computer until a few days ago.
