Did you take a look at that HTML ? You could do that by saving the file 
with a .html extension and opening it in a browser. Maybe it is a web 
page saying that you do not have access to that file. If it is the case, 
that could be caused by Firefox (or whatever PDF viewer you are using) 
not sending the session cookie, or some other problem with the session.

If you actually download a PDF, you should know that there are different 
versions of PDF, many PDF viewers do not support the latest versions 
(which is probably a good thing given the security issues in the latest 
versions), and Firefox has a very limited built-in support for PDF. But 
from your description I have the feeling this is not the problem.
