Comment 15 for bug 1582496

A bit hesitant to add this as I am NOT a techie. However the "GLib-GObject-CRITICAL **: g_object_ref: assertion 'object->ref_count > 0' failed" [etc] output has recently appeared multiple times whilst logging on to Firefox Profile Manager.
Running Firefox 54.0 (32-bit) [= 54.0+build3-0ubuntu0.14.04.1] on ubuntu 14.04. The only plugin is Adobe Flash Player Shockwave Flash 26.0 r0 v. 26.0.0.131 [reported by Synaptic as up-to-date]

This post just in case it helps someone working on this.
BACKGROUND: trying to resolve Firefox crashing in certain websites and when attempting to boot in 'Safe Mode' and/or 'Refresh Firefox'.
I have given much fuller detail at https://support.mozilla.org/en-US/questions/1166052#answer-982419 [unresolved] but if asked can repeat here.
