Some users have problems accessing PDF files with Mozilla Firefox. This is caused by an issue with the built-in PDF viewer in Firefox.
If you are experiencing slow loading times or download errors when trying to view a PDF file in Firefox try one of the following alternatives:
- Download the PDF (right-click and choose Save As)
- Change Firefox settings to use another PDF reader (like Adobe). Instructions are on the Mozilla Support site.
