PDF Security Settings are being ignored by Firefox

Why has Mozilla decided to COMPLETELY IGNORE security settings applied to PDF documents? I have a number of PDFs secured so as to prevent the ability to print or copy text. When opened with Firefox, all of these settings are ignored.

The current state of things, given the existing code:

  • None of these document permissions are enabled/enforced by default in the PDF.js viewer, which thus includes the built-in Firefox PDF Viewer.
  • When the pdfjs.enablePermissions preference is set (in about:config), currently only copying is disabled and the text-selection cursor is then replaced with the "not-allowed" cursor (to indicate that text-selection/copying is prevented); see also PR #11789 and bug 792816 .
  • The rest of the document permissions are currently not implemented.

That doesn't answer my question. Why has Mozilla decided that they don't need to abide by restrictions set by a document's creator?

Do you think everything must have a reason? Perhaps there's only "why should we implement it anyway".

I already linked the full discussion about it. If you need it, just flip the pref.
