From Chrome 42 Silverlight will be blocked

With the new Chrome 42, Google decided to block all NPAPI (Netscape Plugin Application Programming Interface) plugins.

To ignore this block and re-enable plugins (eg. Silverlight) you will need to enable it manually:

 Copy/paste this in the address bar:

chrome://flags/#enable-npapi

The first option is the one we'll need to enable plugins. Click "enable" and reboot Chrome.

This option will disappear anyway on sept.2015, when google will end plugin support.
