I read that article before posting and, unfortunately, it did not help. Thanks.

Ok . Then Use the Adobe Reader plugin to view or download PDF files :- https://support.mozilla.org/en-US/kb/use-adobe-reader-plugin-view-or-download-pdf-files?esab=a&s=I+can%27t+open+PDF&r=0&as=s

Sorry. That didn't work either.

I don't have the Firefox button. No clue why. I deleted and downloaded Firefox again from the Mozilla website and still no Firefox button. And still no PDF.

Thanks....

You can change the action for PDF from Preview in Firefox to use another application like the Adobe Reader or set to Always Ask in

Firefox--> Options/Preferences--> Applications .

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).
