Problem opening PDF with Firefox Android
There is an [app](https://play.google.com/store/apps/details?id=direktoratetforehelse.helsenorge.no) that uses the browser (Android) to open PDFs but for some reason I can't open PDF files using Firefox. It works on Vivaldi and Chrome but not on Firefox. How do I fix it?
