Update: Please see our Java support in Google Chrome article for the latest information about how to view Java content with Chrome. The most recent version of Chrome no longer supports the information conveyed in the article below. macOS users please see Java support in Safari 12.
Google released Chrome 45 on September 1, 2015, and Chrome 46 on October 13, 2015. Unlike its predecessors, neither Chrome 45 nor Chrome 46 support NPAPI plugins like Java and Silverlight. Although Chrome 42 to 44 provided the option for users to enable NPAPI plugins, the option was removed starting with Chrome 45. Quite simply, if you would like to know how to enable Java in Google Chrome 45 (or later), you can’t — at least not directly. But all hope is not lost!
Chrome users who encounter Java content will be greeted by a yellow notification bar at the top of the browser window that says, This site uses a plugin (Java TM)) that is unsupported. The notification also includes a link to more information about why Java is no longer supported by Chrome.
The Java content in the web page itself will display as a gray area with a puzzle piece. If you mouse over the puzzle piece, you will see This plugin is not supported.
If you right-click inside the Java content area, the right-click menu displays application/x-java-applet and an opportunity to Hide this plugin. It no longer includes the Run this plugin selection.
All in all, it is not tremendously helpful information apart from informing you of what is demonstrably obvious. A trip to the Java.com web site would seem to be in order. Perhaps they would know what to do.
Perhaps not. A notification confirms, “The Chrome browser does not support NPAPI plug-ins and therefore will not run all Java content.” For a deeper explanation, click the More info link to visit their Java and Google Chrome article.
