Still having a great UBUNTU experience.
Although, the machine was running SLLLOOOWWWLLLYYY,
so I had a quick loo why this weekend.
Profiling what was running revealed a memory hog by the name of

   plugin-container

ALWAYS using ~80% CPU

After a bit of a dig I found out that this is a security wrapper built
into the firefox suite to 'fix' plugin crashes.

You can get rid of this 'feature' by going to

about:config

Filter   dom.ipc

and set the true attributes to false.

This gets rid of the security wrapper.

Restart firefox.

That takes Firefox CPU use down to 30%-40% CPU even when idle.
The memory managemen is rather poor, so I ditched it in favor of
Opera for Linux.

BIG improvement.

TOTAL CPU now down to 12% including LAMP, Bind9, Postfix etc.
And the whole system is behaving in a better way.

So.  Firefox looks broken for a while.  This happened to KDE.
'Improved' it out of existence.

HTH.
Mark Addinall.
