When using "Preview in Firefox" to view PDF's in the latest version of Firefox (52.0.2), I'm having a problem when I try to print the PDF. I can make the printer default to portrait every time or landscape every time (via the print.printer_printername.print_orientation property). But is there a way to get Firefox to auto-rotate the PDF like other PDF viewers do?
We print a lot of PDF's - equal numbers of portrait and landscape - and having to constantly change the setting in printer settings if very frustrating.
