I can not reproduce it in FF 3.6.8. Could you please upgrade FF to version 3.6.8 by using "Help > Check for updates ..." menu ? Once it is done, check if it crashes again.
Please give a lot more information. What were you doing when it crashed, did you try safe mode, do you have a crash id? https://developer.mozilla.org/En/How_to_get_a_stacktrace_for_a_bug_report
