I have some local PDFs sorted by navigating some local html files. Firefox recognizes that the html files need to be addressed file:///C:/SD_Online/datasc.html. When clicking the link for a PDF it remains c:/SD_Online/L-R4-106.pdf and I get an error saying "Firefox doesn't know how to open this address, because one of the following protocols (c) isn't associated with any program or is not allowed in this context."

I have also seen someone complaining that .txt files do the same thing.
