As of September 1, 2015, Google Chrome will stop supporting an older version of the plug-in architecture known as NPAPI.
The following are the most popular NPAPI plug-ins used in Google Chrome:
Silverlight
Google Talk
Java
Facebook
Unity
Google Earth
The adoption rate of these plug-ins has dropped over the years, so it is unlikely you will be affected. If you find that a Website you visit stops working, try using another browser such as Firefox until the sites move away from using the deprecated, and potentially insecure NPAPI architecture.
