I was looking at pdf.js and noticed that Chrome broke pdf viewing when they started blocking FTP subresources: https://github.com/mozilla/pdf.js/pull/9595.

See: ftp://ftp.sagu.edu/ for some pdf files

It occurred to me that we also broke this by only allowing a narrow set of exceptions.

PdfStreamConverter.jsm probably runs with the system principal. I vote we just allow the system principal to bypass the restriction for now. This would also fix bug 1469536.
