alhough i use netscape, it's a few versions older than mozilla, considering the fact that netscape is using mozilla's engine.
alrik's firefox is one such incarnation of mozilla, just like netscape. it may be better for u to use mozilla (don't get the beta version) instead. al' also right about microsoft not complying to W3 standards for World Wide Web. in fact microsoft never intends to, the way i see it as it keeps implementing more & more stuff which are propriety. function-wise it may be nice & all, but it prevents other browsers (especially if u're using other OS) from browsing MS-loaded webpages properly. that's not friendly at all.
one of the thngs i love about mozilla or mozilla-based browsers, is that u can disable pop-ups. IE is still talking about implementing this in future upgrades.
