I have latest flash plugin from adobe.com installed:

flash-plugin-10.1.82.76-release.i386

Also, this cpu load by the flashplugin was there in spite of the fact I 
had no flash playing on firefox.

So, I killed the process (not firefox).
I then played a youtube video, sure enough, cpu usage sckyrocketed to 79%.
I stopped the playback in FF and flashplugin now looked reasonable, but 
still
using the cpu:

   PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
  6645 jd        20   0  221m  39m  18m S  7.6  2.0   1:20.51

So, Iwhat in blazes is it doing when I have nothing playing?
7.6% of cpu is a whole lot of cpu for doing nothing!
Does Adobe read this list??? They should take note!!
