Have you heard of or tried
Comodo Dragon or
SRware Iron? They both run on the
chromium platform (very similar styles as well)
Comodo is a software security and firewall company so supposedly they are touting the browser as exceptionally secure
Chrome is supposedly one of the faster of the browsers - I think this all depends on your hardware and Internet connection, cuz my FF is pretty quick even with a bunch of add-ons.
