So I've done some more testing of this with various linux_base-* 
installs.  Youtube and most things (google maps) work with sound just 
fine for a few seconds, but after trying to interact or letting them go 
for a few minute they begin to rapidly eat up main memory.  
npviewer.bin's usage will top out somewhere around 300-450MB before it 
core dumps: pid 77684 (npviewer.bin), uid 1042: exited on signal 11 
(core dumped).  This is on FreeBSD 7-STABLE i386 (as of Tue Oct 28) with 
native Firefox 3.0.3 still.
