Mac users: Having Firefox pdf download problems?

I am. I was getting a blank white screen when I tried to download Pro reports in PDF format. Adobe’s PDF plugin isn’t very friendly with the latest versions of Firefox on MacOS. Here‘s a solution:

If you want to use Adobe Acrobat, you can just change the preference that was messed up:

Go into Firefox > Preferences > Applications and look for “PDF file”

Next to that, select use Adobe Acrobat (or use Preview) rather than Adobe Acrobat NPAPI 10.1.3

My preferences listed the document as “Preview Document (application/pdf)”
