Last time I tried it, Netscape sucked...
then you are saying Firebird/Mozilla suck too, since the last Netscape browser was powered by the same Gecko core engine that Firebird and Mozilla use. I say "was" because as I understand it, Netscape is dying off to be replaced by Mozilla-based browsers.
if you are referring to something like "leaving/entering non-encrypted pages", etc., then you either forgot that you did the same when you first started using IE (IE6 asks the same questions until you configure it to do otherwise), or you have your security settings down too low for IE to care (poor you!).
besides, it takes a simple click of a check box and those windows won't aks you again.
