Also, as of this time, Safari will not do RTE’s. It is a limitation of the KHTML/WebKit engine Safari is based on. See this page for more details:

For me, it doesn’t get any better than FireFox with the web developer plugins. I use camino as well, but the browser is seriously lacking in useful features, plus it is full of irritating little nuances like when I tab in FF or safari, it tabs through all the form boxes on the page, then to the URL bar on top. In Camino, it never goes to the URL bar.
Another promising looking browser is the Sunrise Browser [
