Apps to translate web pages and many other types of documents to PDF are growing. My home page is filled with links to personal PDFs that hold information I may need rapidly on my phone. I keep them on a server. The ability of a phone browser to display a PDF is becoming as valuable as being able to display HTML. Please tell us the best way to configure the Android Firefox to display links to PDFs.

What is really discouraging is that sometimes it works and sometimes it doesn't and I have no idea if I changed something or you. And your advice seems to change too. SO.....please come up with advice for an app to add or your own internal PDF display feature.
