Why does Wolfram Research no longer support the CDF plugin?
Wolfram Research no longer releases or supports browser plugins for Wolfram Player because major browsers have stopped supporting NPAPI plugins.
We instead recommend the Wolfram Cloud for deploying Wolfram CDF documents on the web.
We also recommend viewing CDF files offline using the Wolfram Player. If the CDF document you are trying to view is not downloadable, please contact the according author for access.
