[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 :

Code:

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

Code:

layers.offmainthreadcomposition.enabled = true
as well.

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

Code:

env MOZ_USE_OMTC=1 firefox
Hope this helps :)

Hmm.. This happens when I try to type an address:
Code:

$ env MOZ_USE_OMTC=1 firefox
