IE
for viewing friendster profiles
capable of displaying more sites. can read almost all kinds of scripts too.
FireFox
multiply & freewebs (coz they hang sometimes in other browsers)
my other friendster account - homepage only (i have lots of friendster accounts -- one account for each browser, so that i won't need to logout everytime i check them all)
filters scripts. ruins my layouts.
Opera
for general sites.
i like how it displays new tabs; smoother than in IE and FF. and it's neat too.
Netscape
i've just downloaded one, minutes ago. hehe
but i like its interface though
