firefox will not start

Binary package hint: firefox-3.5

Clean load of karmic with all updates. Launch Firefox, it begins to start, then goes away with no error messages and nothing from apport. Network working since can do updates and samba file transfers. Machine is an old Celeron/G945 system I am trying to repurpose as a NAS. System ran gutsy and firefox-3.0 fine. A suggestion for another web browser I might use would help sending debug information to you.
