The built in browser versions of reader are crap, one of the standard software additions to our builds is the latest version of acrobat reader.
Acrobat Reader DC.
Web Browser versions are invariably missing features or have display bugs. The initial Windows 10 machines went out at work with no Acrobat and the users bitched and complained that Edge was screwing things up like you wouldn't believe. So it got added back into the image...
We checked Foxit, but as suggested above it's a bloated PoS now.
Not sure what these pdfs are containing but I have never once installed a 3rd party pdf reader with windows 10 and I use PDFs on a daily bases and never once had compatibility issues or screwing up things anywhere else.
Can't remember off hand, but it was output from systems type stuff, not the typical manual or someone's CV Word spat out.
Edge might be better now, it gave us trouble when 1511 launched.
