I also had this happen trying to open a PDF in Firefox recently.
- brudgers 9y agoIt will happen if: about:preferences#applications -> Portable Document Format (PDF) -> Use firefox is set. A fix is to set about:preferences#applications -> Portable Document Format (PDF) -> Preview in firefox The problem can be caused (in Ubuntu 16.04) by selecting Firefox as the system default for PDF viewing.
