BONGO_X I love it. Safari is OK, I like Camino and it was my default browser for a long time. No browser I tried was exactly what I wanted so I went searching and tried icab, which I hadn't used since OS9. It has everything I want, every feature, and is totally customizable. The only issue is that some of the features are not obvious and are easy to miss. Everything I thought was a shortcoming was soon proven not to be with an email to the developer.
So I gave him my $25. Well worth it.
