When I terminate Firefox with Ctrl+c or SIGTERM (via pkill), the
contentproc child processes leave 3 or 4 core dumps on my system.

The tracebacks look like this (see attached for full tracebacks):

Core was generated by `/usr/lib/firefox/firefox -contentproc -childID 3 -isForBrowser -intPrefs 6:50|7'.
Program terminated with signal SIGSEGV, Segmentation fault.
