FreeBSD 11.2, X.org, Xfce, and Firefox issues

[David Christensen]

freebsd-questions:

I have installed FreeBSD on a Dell Inspiron E1505 laptop.  My goal is to 
use it as a desktop/ workstation on my SOHO network:

root at ragnar-ssd:~ # freebsd-version ; uname -a
11.2-RELEASE-p9
FreeBSD ragnar-ssd 11.2-RELEASE-p9 FreeBSD 11.2-RELEASE-p9 #0: Tue Feb 
5 15:30:36 UTC 2019 
root at amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC  amd64


I have also installed:

root at ragnar-ssd:~ # pkg info | egrep '^(xorg-7|xfce-|firefox-)'
firefox-66.0.2,1               Web browser based on the browser portion 
of Mozilla
xfce-4.12_1                    The "meta-port" for the Xfce Desktop 
Environment
xorg-7.7_3                     X.Org complete distribution metaport


When I start Firefox via an Xfce panel shortcut, it starts.  But when I 
try to browse to a URL, it core dumps and the Firefox window spins 
attempting to connect to the URL:

         root at ragnar-ssd:~ # tail -n 1 /var/log/messages
         Apr 29 19:53:03 ragnar-ssd kernel: pid 899 (firefox), uid 
13250: exited
on signal 11 (core dumped)

         2019-04-29 19:55:28 dpchrist at ragnar-ssd ~
         $ ll firefox.core
         -rw-------  1 dpchrist  dpchrist  127205376 2019/04/29 19:53:03 
firefox.
core


When I start Firefox via Terminal:

	2019-04-29 19:46:51 dpchrist at ragnar-ssd ~
	$ firefox

	(firefox:884): GVFS-RemoteVolumeMonitor-WARNING **: 19:46:58.095:

Browsing seems to work.


When I close the Window:

Any suggestions for fixing Firefox?
