Netscape used to be good once, now I only use FireFox. However besides the download manager and the tabs the Internet Explorer is a good browser as well. Moreover, many internet contents (including my website... sorry) aren\'t made for FireFix and won\'t be shown correctly with this browser. If you\'re using windows and/or msn, you\'ll need IE anyway. Download managers can be installed seperately for Microsoft\'s browser, too. If you just want to browse securely, get yourself one of the best AntVirus softwares (including firewall, system check and everything) ever, and this even for free, on
this website.
Hope I could help you a bit.
