I'm staying with 3.6.16 for now as FF4 doesn't support our Zone Alarm Extreme's Browser protection, hopefully they will get that fixed soon.


FF4 is very customizable if I recall, I only tried it a short time and dh or ds picked up a pesky little bug so i went back to the old version for the extra ZA protection.

you should be OK kitty, security wise and they may make some changes to FF4 due to input from users.
