I'm a little leery about updating to 3.0 in the light of Firefox problems caused by other security product firewalls every time there is an update. There are numerous threads about this at Mozillazine forums, none so far regarding nod32. It seems these firewalls can be a little too vigilant and intrusive, I would hate to install and find the next time FF updated I could no longer get onto the net or worse. Any feedback would be appreciated. Edit: The firewall only applies to Smart Security not 3.0 AV I guess.
