Hi Shengchieh,
I'm on LL 2.0/64 and my system has already, a few days ago, automatically upgraded to FF 34.0 - menu > all > install updates. Have you tried running install updates recently?
I will boot my LL 2.2/64 in VirtualBox and see if there's any problems there.
Edit: Just verified LL 2.2/64 is also running FF 34.
Maybe a copy of my /etc/apt/sources.list will help?
