Problem running lxde and iceweasel in wheezy

[Halim Sahin <halim.sahin@freenet.de>]

Hi,
Ok it seems gnome-3.4 is not much usable in wheezy due to posted
stability problems.
Unfortunately xfce
is at 4.8.
so I installed lxde and got a11y working except iceweasel.
What I did:
export GNOME_ACCESSIBILITY=1
export MOZILLA_ACCESSIBILITY=1
export GTK_MODULES=gail:atk-bridge

Now iceweasel report when started in terminal gtk accessibility module
initialized.
Thats it.
Orca can't read anything inside firefox/iceweasel.
I have also tested a plain firefox from mozilla.org (same result).
Any idea what's wrong there?
Thx in advance.
Halim
