See this post:
For security reasons, Google is removing support for NPAPI plugins from Chrome Browser starting version 42.x.
To see Chrome Version, go to: chrome://version/ in Chrome.
This means for example:
- Applications based on Java will not work in Chrome,
- Adobe Dynamic Forms (XFA based PDFs) will not display as a plugin inside Chrome
- You must enable the native PDF Viewer in Chrome to display other types of PDF inside Chrome.
- There is a temporary work around until September. Read the post above for details.
We need to find from Adobe what is the future of displaying Adobe Dynamic PDFs inside Chrome Browser?
