Firefox can be configured to use an alsa plugin or esd-compatible
soundserver. Check the file /etc/iceweasel/iceweaselrc (or
/etc/firefox/firefoxrc as appropriate). The line to use pulseaudio is
"ICEWEASEL_DSP="padsp" (or FIREFOX_DSP="padsp"). With the alsa jack
output plugin, or the pulseaudio jack output backend, you can even
make firefox and its flash plugins go through jack.

For what it is worth, I have a dual-core 3.2 gigahertz pentium 4 with
1.4 gigs of RAM in my main machine, and flash video playback often
pegs one of my CPU's to nearly 100%. If there are more than three
flash video objects active at once on one page it often stalls
iceweasel to a complete halt, if not crashing it entirely (I presume
it is some kind of race condition or re-entrancy problem with the
Linux version of the adobe plugin). I work around this latter issue by
using the flash-block plugin, which shows a play button for each flash
object that does not load the flash plugin until you click on it.
