Hm, I can't reproduce it on f8/i386, it may be x86_64 specific... 

Can you please try to run it in safe mode? (firefox -safe-mode)

Kay, those null pointers don't look sane...any thoughts?

When using "firefox -safe-mode", firefox doesn't crash anymore.
I have restarted firefox without parameter, disabling another extension each time until firefox doesn't crash.
The culprit (maybe only the trigger) was FoxyProxy, a 100% javascript extension. This morning, version 2.8.8 was available, since the update, no crash has occurred. I haven't found any changelog about the new version.

It seems the problem has been reported on foxyproxy web site a few days ago:
