Iron Portable from PortableApps is a fully functional browser that its makers tout as the browser of the future. The browser is based on the same Chromium source code as the Google Chrome browser, but it doesn't have the unique IDs, time stamps, and other components that allow user tracking and other privacy-compromising functionality.
The browser presents a simple no-nonsense interface and is used just like any other browser. Chrome users will note the obvious similarities between the two browsers. In fact, since they're based on the same code, they have compatible add-ons and extensions as well as themes. The Iron toolbar offers direct links to an image hosting site, the Iron Forum discussion site, and the publisher's Web site. The browser performed as any other browser would. The only difference we noticed was that it does not make suggestions when you type something in the Web Search box.
Users won't see much of a difference between Iron Portable and other browsers, but security-minded folks (or those that just like their privacy) will like the under-the-hood safeguards that Iron Portable offers.
