Hello !

I have a physical machine with Centos 7.6.1810 and Firefox 60.9.0-1.el7.centos installed.

I start a Xvfb, and try to start firefox, and get this output: Running without a11y support! 

 (firefox:7740): GLib-GObject-CRITICAL **: 23:18:17.497: g_object_ref: assertion 'object->ref_count > 0' failed
 Segmentation fault

I tried to install a virtual machine with same OS, over VirtualBox in a Win10. Same OS, same firefox rpm. I start a Xvfb and try to start firefox, and works fine.

So my physical machine has something that makes Firefox to crash and do not start.

Can someone help me ?

I have compared packages installed in the physical machine and the virtual.

I have upgraded some packages in the physical machine, in order to match the version installed in the virtual machine.

With this procedure, Firefox starts in the physical machine.

An older version of a package was the cause of the problem. The suspicious package is "gtk3", but I'm not sure. I upgraded over 15 packages.
