Little update from me:
I'm now using
Firefox Ver. 22.0-1
glib 2.36.3-2
Kernel 3.9.9-1-ARCH

And Firefox does not crash immediately at startup and is normal usable.
Firefox still crashes sometimes though (like once within two hours).
The error message: (process:755): GLib-CRITICAL **: g_slice_set_config: assertion `sys_page_size == 0' failed
Still shows up directly after startup of the browser.
