Hi All,

SL 7.3
firefox-55.0.2.x64.tar.bz2
Scientific Linux 7.2 (RHEL clone)
$ cat /etc/redhat-release: Scientific Linux release 7.3 (Nitrogen)
uname -r: 3.10.0-693.1.1.el7.x86_64


I just ran an update on Scientific Linux 7.3.  Firefox will
no longer start, including safe mode or the profile manager.
Firefox goes straight through to the crash reporter.

Running ff from the command line gives:

         (firefox:19909): GLib-GObject-CRITICAL **: g_object_ref:
         assertion 'object->ref_count > 0' failed

         ExceptionHandler::GenerateDump cloned child 20002

Any words of wisdom?


Many thanks,
-T
