Summary
From April Chromium will no longer play Flash content using the “old” Adobe plugin
The change is due to the arrival of ‘Aura’ for Linux which lacks coded support for NPAPI plugins
Other NPAPI plugins affected include Silverlight, Google Earth and Facebook Video
The ‘Pepper Flash’ plugin bundled with Google Chrome will continue to work
But ‘Pepper Flash’ is not (currently) available for download and is only shipped in Google Chrome
update: Install Pepperflash In Chromium | Debian Bits And Snips
