hi all

Recently I've downloaded and install mozilla 1.1, it is first time I am using Mozilla ( I use Opera too ). When I run Mozilla the ZoneAlarm pop ups two messages, the first one is Mozilla wants to access to Internet and the second one is mozilla wants to act as server.
The first one is ok with me but I want to know why Mozilla like to act as a server unlike other browsers! and I'd like to know if this might be safe or not.
BTW even if I do not allow Mozilla to act as a server I can surf the web and nothing seems to be wrong.

Thanks all.
