No need to download to anything other than localstorage.
There have been a half dozen vulnerabilities found in the Firefox extension code exploitable through PDF.js over the years, but this is a far better record than the hundreds of vulnerabilities identified in Acrobat Reader.
PDF.js does a lot less than Acrobat. It's much more focused on just displaying articles, and less about rich media interactions like embedding 3D models, Flash, videos, etc. in the PDF.

Very much appreciate you pointing this out. Do you know if I can use this to embed a pdf in a personal website. a resume for example?
