Comment 8 for bug 1278942

I've also executed

$ GTK_MODULES=gail:atk-bridge:overlay-scrollbar:unity-gtk-module

and restarted both Onboard and Firefox, both to no avail. The above modules are of course now loaded (the output of env | grep GTK_MODULES confirms this), but Onboard still doesn't 'see' Firefox (trunk or stable).
