well I think it comes down to a matter of preference or choice ya know. some people feel more secure with a firewall while others might not feel a need for them so it's really moot to debate it on here lol

to be honest with u my friend said firefox is a lot better than explorer but i never actually tried firefox so i dunno, but i am content with explorer even though it has given me headaches in the past lol. i jus had to whoop its butt a lil into shape ya know lol
