[Firefox] v28 breaks HW acceleration fix

Hi folks,

I'm just sharing a fix for Firefox v28 and the Nvidia blob.

Firefox v28 no longer offer HW acceleration with the following trick :

 layers.acceleration.force-enabled = true
Now, you have to set

 layers.offmainthreadcomposition.enabled = true
as well.

Finally, you have to run Firefox with the following command :

 env MOZ_USE_OMTC=1 firefox
Hope this helps

Hmm.. This happens when I try to type an address:
$ env MOZ_USE_OMTC=1 firefox

(process:23587): GLib-CRITICAL **: g_slice_set_config: assertion `sys_page_size == 0' failed
Fontconfig warning: "/etc/fonts/conf.d/50-user.conf", line 14: reading configurations from ~/.fonts.conf is deprecated.
