I don't think it worked with previous versions of Firefox, I tested and the rendering is broken too. In some old versions, the PDF loads endlessly or displays a blank page.
In the current version of Firefox, only the vertical text is displayed, the scanned part is not.

Console log:
"PDF 15f3a4498224fea5b56791fac35d45f [1.4 PDF4NET 2.9.1.0 (http://www.o2sol.com/) / -] (PDF.js: 1.0.277)" viewer.js:3465
