I used dom.ipc.plugins.enabled.npwrapper.libflashplayer.so false
(in about:config in Firefox) as a workaround for some youtube videos to play.
But eventually it caused that same problem with Street View in Google Maps.
So, I had to set dom.ipc.plugins.enabled.npwrapper.libflashplayer.so
and dom.ipc.plugins.enabled back to default true, that helped with Street View.
Surprisingly, the youtube videos which earlier gave the error message
(about Flash) are played successfully now.
