Answer 1

There is no javascript api to check NPAPI support, but as workaround I can suggest you to check browser version of Chrome.

If Chrome version older then 42 than NPAPI support is disabled. Yes, from 42 and before 45 version you can use chrome://flags/#enable-npapi but there is no way to check this flags from JS

For now I guess it's pretty actual information: https://www.chromium.org/developers/npapi-deprecation?pli=1
