The "portable document format" icon is a Word 2010 icon, so selecting Adobe Reader as action does not work to display the PDF.
In the Applications tab -- Content Type -- the "portable document format" icon is a Word 2010 icon (not Adobe), so selecting Adobe Reader or preview in Firefox as action does not work to display the PDF. I can see this Applications difference because my other Firefox laptop has the Adobe icon, and I can view PDFs. Essentially, a PDF is coming in as a Word document -- and the computer tries to open it up as a Word file.
How do I get the correct PDF icon in the Applications list -- the same way it displays (and works) on my other laptop.

I think you need to add this to the list of applications and the action to take on the type of content. This can also be managed in the about:permissions page. Permissions Manager - Give certain websites the ability to store passwords, set cookies and more
