http://www.pryan.org/mozilla/seamonkey/djeter/ is where I got my latest build of Mozilla. It seems that people are really favouring Firefox over Mozilla; I like the all-in-one idea and unless Mozilla falls behind I'm going to stick with it. In any case; at the link above there are several builds for various OS's and hardware here. I haven't measured anything, but it sure seems pretty snappy having a i686 compiled version with SSE2 extensions.
