I have now updated all packages, including alsa-plugins. Firefox uses
Pulseaudio as audio output.

Firefox uses ~150% CPU (cpu usage via top, raw momentary cpu %, not weighted)
when playing the following video from Youtube on 720p:

My laptop has 2.6 Ghz i5 processor and Intel HD4000 GPU, so I think my hardware
should definitely be on par with the task of playing the above video on 720p,
and the CPU usage should not got above 100% ...

I will try compiling/installing Firefox without Pulseaudio, and see if I get
any better results.
