Yes, the other computer I used has an older version of firefox.
Hmmm. I just discovered that this seems to be a problem w/my computer, not w/my WordPress site. Suddenly, my Firefox browser will not download pdf files from anywhere. On a different computer, the pdf files download fine for me. Sorry to bother you!
Thanks for your response. Yes. I can add a page, upload a pdf file to the page, and publish the page. When I go to the page on my site, the pdf link is there. Clicking on the link opens a blank page, but the pdf does not download. I am left with only the blank page (which has the same title as the link).
