I use opera, netscape4.7, firefox, text only and IE - all have their pluses and minuses - mainly to do with plugin support...
but the most I use opera, then firefox, then ie, then netscape, then text only browser - when I use ie - I use a batch file to make all the registry changes that I need to make my c**p work because ie can be a pain....
netscape I only use now and again where some sites have netscape4.7 only features... - but generally only for known sites - I cannot be bothered with any site which says best viewed in " xyz " ....
netscape 4.7 has a few bugs, so it lets me know if someone has good java coding or bad....
