No problems here with the PDF links under both sections. They open for me the built-in PDF Viewer in a tab.

You can set the pdfjs.disabled pref to true on the about:config page to disable the build-in PDF viewer.

You can check the value of the plugin.disable_full_page_plugin_for_types pref on the about:config page and remove the application/pdf part if present or reset the pref to the default via the right-click context menu if you want to display PDF documents in Firefox with another application (i.e. not the built-in PDF Viewer).

Is this with opening a direct link to a PDF file in a Firefox tab?

If this isn't working then the server might not send the PDF file as application/pdf.

Under the convert web pages to PDF tab: Options I selected Use PDF Plugin instead of Use OS Default viewer. That fixed it.

Thanks for getting me going in the right direction.
