Public bug reported:

Every time I logout or shutdown the system with firefox open, it will
generate a crash report in about:crashes. However, there is no crash
dump in /var/crash.

I noticed this before I upgraded from 18.04 LTS recently, and at first I
thought the crash went away after the upgrade, but sadly it's not the

I've tested with a fresh new user, with the same result. I'm running
Xubuntu 20.04.1 LTS.

This may be the same bug as bug #73536 ( Mozilla Bugzilla #336193), but
I can't be sure.

To reproduce:

Open firefox. Logout with firefox window open. login again and check
"about:crashes" in firefox.

The output of:

lsb_release -a; uname -a; apt-cache policy firefox
