SRWare Iron browser is based upon the open-source Chromium browser, from which served as basis for the famous Google Chrome browser. It works very much like Chrome (fast, intuitive, secure and efficient) but actually it doesn't favour the Goggle server, by submitting entries about the user id or any private data.
A portable version (install the browser on a USB key) is also available.
Actually this browser comes with many innovative features and a lot of promises. But still it is needed that SRWare Iron to become as popular as the other browsers. For now it is only available for windows XP and Vista.
