But users are provided option to manually enable support of NPAPI plugins. Popular plugins like Java, Silverlight and other ActiveX control are all run by the NPAPI plugin interface in Chrome browser. Chrome has deprecated support of all NPAPI plugins since Chrome 42.

It was the first real way for developers to add functionality to browsers, which were still emerging at the time.
