I was curious and wanted to see if I could start Firefox using Terminal. So I typed


in Terminal, and it displayed the message below

(process:5199): GLib-CRITICAL **: g_slice_set_config: assertion 'sys_page_size == 0' failed

And Firefox started running. But I am a little worried because the message above looks like an error message to me. Can anyone tell me what it means?


It always happens with me too. They say it is a bug but to my experience, it doesn't affect performance at all. So you may ignore the message and continue using Firefox
