ACK. Now I find that my privacy protection was disabled (I didn't do this) in DB and I can't change my protection level from permissive back to the default. My identity, restigry, cookie and ****** control all disabled... How do I change this??
I'm having the same problem and after reading this thread I've manually updated BitDefender and tried to reinstall FF twice, but BD is still coming up with Trojan.Generic.1607990. I turned on the game mode while I reinstalled FF (after manual updating BD). Seemed to work okay for me. I'm back in FF. thank God.
