Notice how you got a couple nsplugin instances running there with flash. When 
you close down programs, did you close just the windows you saw, or you went 
with killing the processes by PID? Try killing just the flash instances by PID 
and see what it goes. I have noticed similar problemas and it usually happens 
with stuck flash videos that doesn't close properly when you close down the 
browser window (and firefox is really worse in that regard than chrome, but 
usually crashes less than the later).
