Thanks for your reply. Did you find the proof of the root cause of my crash from the crash report?

If what your said is true, the firefox is to blame for its robustness. Many software applications may encounter RAM shortage. However, how many of them will crash themselves to tell the user that RAM is not enough? Firefox is among the few.
