pdf.js does a lot less, just how I like it. I can view PDFs and not have a constant stream of critical vulnerabilities to worry about.

Did you know Acrobat supports viewing 3D models in PDFs? Not even kidding[1]. It has an unnecessarily huge attack surface.

I will never use that and I work in engineering at a factory.
