For ages now I've used Sumatra PDF: https://www.sumatrapdfreader.org/free-pdf-reader.html
It's fairly lightweight and easy to use, so satisfies your first paragraph. However, I don't think it's open-source. I'm not sure exactly what you mean by the "Explorer side box", but there's many different ways to use Explorer. Regarding Firefox, it has a built in PDF viewer, so that's what I use.
Either way, it's easy enough to try.
