Hi, did you look in the ~/.xsession-errors file?
Also maybe you could explicitly confirm which desktop
environment you are using, so we're not guessing.
Perhaps try starting firefox from a terminal so you can see if it emits
any error messages when the crash happens.
Maybe there are dbus logs somewhere?
These are just basic suggestions, maybe others here will have
better ideas.
Aside: have you looked at 'htop', it has a much nicer user interface than 'top'.
