" This pdf document might not be displayed correctly " - Blank text in PDF files

more options

How is this still a thing? Chrome can open any PDF file correctly. Any PDF file I open in Firefox shows the text as blank spaces, and I get the message "This pdf document might not be displayed correctly". Why? Why do I, with Firefox, need a 3rd party PDF reader? I shouldn't have to. Even Microsoft Edge gets this right.

Back to Chrome, I guess...

Every single PDF from everywhere you've tested?

The pdf.js viewer used in Firefox renders the PDF as one HTML canvas per page. To provide for searchability, it positions a layer of transparent text in front of the canvas. If Firefox is displaying the graphical elements of the PDF but not the text, I wonder whether there might be a font problem on your Firefox?
