Something totally not right here.....

To begin, how can you have 2 copies of Firefox running by "tommy"?

 From my experience, Firefox will not run for a user if it is already 
running for that user - in this case "tommy".

A question: if you had already mentioned it I have forgotten already :-( 
but which version of Kubuntu are you running, which version of KDE, and 
which version of Firefox?

And what is that PID, called jdb2/sda1-8, which is taking up most of the 
cpu? It is owned by root. So what is root doing with this jdb2-thingie?
