I've tried all three. Opera 5 is faster, smaller (2 Mb) and more stable that Mozilla 0.8 (10.5 Mb) but doesn't yet allow java support. Mozilla's mail program is also much nicer than Netscape 4.7 and I haven't made it crash yet. Mozilla is quite a bit faster than Netscape 6 but still takes too much time to start. A lot of the features don't work or make the progam crash. I've got the CUPS web interface to work with Netscape 4.7 and Mozilla 0.8, but not Netscape 6 or Opera 5. CUPS is still quite temperamental. I use it because it supports my Epson printers through the gimp-print plugin and so I can get high quality printing from a wide range of applications. QtCups is a neat add-on that allows you easily to set printer preferences at print-time. JDL
