On my Fedora system, firefox is a bourne shell script which calls
run-mozilla.sh (which is another bourne shell script) which, in turn, calls
firefox-bin which is the binary.  Within run-mozilla.sh, there are --debug
options available but these require the use of a debugger.  There is a
moz_usage function in there (which doesn't tell much) but no way of calling
it.  I've attached a patch for run-mozilla.sh that will add a (-h | --help)
switch to run-mozilla.sh .

Anyway, to use the debugger, you could modify the run-mozilla.sh call within
/usr/lib/firefox/firefox to add the -g switch.  Then, of course, you need to
know how to use a debugger (which I don't)...
