The latest release of Google Chrome includes the Chrome PDF Viewer which won’t properly display some PDF files like Dynamic Forms and PDF Portfolios. While Google Chrome is not a supported browser, the Adobe PDF Plug-In For Firefox and Netscape 10.0.0 does actually work with Chrome on Windows.
If you want to display your PDF files in Chrome using the Adobe Reader, you can easily disable the native viewer. Just type “about:plugins” in address bar and then disable the Chrome PDF Viewer. You don’t even need to restart.
