[SOLVED] [Firefox 19] How do I get Firefox to display local PDF files?

When I first installed Firefox 19, the PDF viewer worked so well that I uninstalled Adobe Reader. Today, after a system update, Firefox stopped displaying local PDFs. If I open a PDF directly from a website, the internal PDF viewer activates and the PDF is displayed properly. However, if I open a PDF from my hard drive, Firefox just displays a mass of jumbled characters and the internal PDF viewer does not activate.

Here is a screenshot of the behavior:

I tried running in safe mode and the behavior persisted. I really hope there is a fix for this because using Firefox for viewing PDFs really makes my workflow much better.
