A blank tab opens in Firefox every time I open a .pdf file. I've noticed several people have this issue but no sufficient response has been posted yet. It is incredibly annoying, especially since I may open multiple pdf files at once and when I return to Firefox there are several blank tabs open.

Are you using the built-in PDF Viewer (pdfjs) or the Adobe Reader, either in Firefox or standalone?

According to my options, PDFs are supposed to be viewed using Adobe Reader and not viewed in Firefox. PDF files do open in Adobe, but a blank tab still opens in Firefox when I open them.
