When I open my Firefox Web Browser from the terminal I get these following warnings.

william@william-AO722:~$ firefox

(process:5672): GLib-CRITICAL **: g_slice_set_config: assertion 'sys_page_size == 0' failed

(firefox:5672): GLib-GObject-WARNING **: Attempt to add property GnomeProgram::sm-connect after class was initialised

(firefox:5672): GLib-GObject-WARNING **: Attempt to add property GnomeProgram::show-crash-dialog after class was initialised

(firefox:5672): GLib-GObject-WARNING **: Attempt to add property GnomeProgram::default-icon after class was initialised

Is there a way that I can get rid of these warnings?

Also can anyone tell me what GLib is and what is it for?

I am running Ubuntu 13.10
