Hi everyone, by going to the PDF.js github page and running the [https://mozilla.github.io/pdf.js/web/viewer.html demo] I've noticed that you can open PDFs directly from PDF.js in Firefox. Is there a way to access PDF.js without opening a file first? What I'd want to do is go to an empty session of PDF.js and from there choose the file I want to open, without having for example to load the demo document first. Thanks to anyone that will help :)
