NPAPI support has been disabled by default by Chrome developers as of Chrome 42. The NPAPI is the plugin architecture used by many plug-ins such as the Java plug-in to function in the browser. While the NPAPI can still be enabled in Chrome through a flag, the Chrome developers are planning to completely drop the NPAPI support in a future version of Chrome.
Please see here for more details on how to use Java in Chrome 42:
Once Chrome completely drops NPAPI support, the Java plug-in will no longer work at all in Chrome. Since edit-on NG and edit-on Pro require the Java plug-in, they will also no longer be able to support Chrome. There is nothing we can do about this.
It is possible that Oracle will go ahead an develop a Java plug-in that supports Chrome. If this ever happens, we will do our best to support Chrome again.
