Dick,

   In the firefox frame, when you follow the menus Edit -> Preferences ->
Applications what do you have for an application for PDFs?

   Here, (firefox-38.4.0; Slackware stays way back from the bleeding edges),
my preference is to 'Save File' while the other options are 'xpdf (default,'
'Adobe Reader 9.5 in firefox,' and 'Other.' Perhaps selecting 'Other' and
specifying what you want to use will help.

   xpdf (at least the Slackware-14.1 version) does not handle pdf-1.6 or -1.7
which is commonly used now by almost all microserfs; mupdf is an alternative
that works with all PDF versions.

HTH,

Rich
