Comment 11 for bug 1411858

I've just checked my other machine, which is also running utopic lubuntu, and a generic 3.16 low latency kernel, and firefox is showing flash and silverlight in the about:plugins.
So, I've just tried running it at youtube and a pipelight error occurred so I ran sudo pipelight-plugin update, and then restarted firefox. The updated flash installer worked and then at youtube it used the html5 player. I then checked the plugins and flash is *not* listed anymore(?). I went to netflix with uacontrol installed and got a 'pipelight error during initialisation'.
On this machine thought, Midori hangs at youtube even with the html5 player.
