One of the easiest ways is to start Firefox from inside a
regular X terminal (classic xterm program works fine) to
capture possible text output (if nothing is logged in the
file ~/.xsession-errors, or if there is "too much noise"
inside that file to determine what messages belong to the
Firefox startup process).

For a more verbose output, run "truss firefox" in xterm.
This should provide you a good impression of what's happening.
