Can anyone tell me what my options are?

You can try out the latest development version of the PDF viewer (pdfjs) to see if that version works for youe.

For an external app, there's always Adobe Reader.

xpi link download says it cannot install as it does not work with firefox 57

You need a Developer Edition or Nightly Firefox build (Beta won't work as well) that supports Legacy extensions to be able to use the PDF developer version.

I do not want to use neither 'Legacy extensions' nor 'PDF developer version'. All I want is to make Firefox built-in PDF Viewer (pdfjs) work in standard release version.
