I've been using Avant Browser for a year now and I have to say that I don't know how I did without it! Great support forum, responsive author--one guy, Anderson Che, is the developer and the program has been evolving ever since I started using it. It stops pop-ups, plays well with most download managers, has a Google search bar, the current beta has ad-block, right click translations and the whole kit and kaboodle is skinnable!
