PDFs opened as Preview Documents

For some reason, Firefox considers some pdf documents to be "Preview Documents," which means that instead of previewing the document in Firefox without downloading, I have to download it. Once the file is stored on my computer, I can open it as a pdf in Firefox without any issues.

Is there a way I can disable Preview Documents as a content type and have Firefox recognize all documents with a .pdf extension as a pdf?
