Package: firefox-esr
Version: 52.7.2esr-1
Severity: normal
File: /usr/lib/firefox-esr/plugin-container

When I terminate Firefox ESR with Ctrl+c or SIGTERM (via pkill), the
plugin-container child process leaves a core dump on my system.

The traceback looks like this (see attached for full traceback):

Core was generated by `/usr/lib/firefox-esr/plugin-container -safeMode -greomni /usr/lib/firefox-esr/o'.
Program terminated with signal SIGSEGV, Segmentation fault.
