@antezz: I've tried exactly what you suggest but somehow to kill the daemon and processes completely is impossible for me. They are up and running immediately after I kill them. Could you please advise detailed commands? I've tried kill -9 browser* and others but no success.

Edit: Of course I did it under the root user ;-)

Edit2: I've tried:
ps -ef | grep browser //to get the pids of processes
and then kill the processes manually.
In the past I used to know how to write the command using awk and piping the pids directly to kill command so they are all killed in one moment. Out of my abilities now. Anyway, it looks there is something else which starts the browser processes.
