With default firefox 41.0.1,1 and alsa-plugins 1.0.29, firefox has high cpu
usage when playing html5 video.
With an i7-3612QM, firefox uses >130% CPU when playing 720p youtube video.

If I enable BUFSZ_P2 for audio/alsa-plugins, CPU usage reduces to ~50%.
If I switch to other backends for alsa(like pulse), CPU usage also reduces.

Please set the default value of BUFSZ_P2 to "ON" for alsa-plugins, or fix
alsa's oss backend.
