Windows/Mac/Linux: Lightweight web browser Arora uses the same rendering engine as Google Chrome and Safari, but works on almost any platform.
The browser offers most of the features of mainstream browsers, including private browsing, session management, and a smart location bar—all in a lightweight browser that opens nearly instantly. It's unlikely that Lifehacker readers will leave their precious Firefox behind for this, but it's a nice, functional, and fast browser that's definitely worth a look—especially for Linux users interested in a functional WebKit browser with a private browsing mode.
Arora is free and open source, available for Linux, Mac, Windows, or even FreeBSD. In our testing on Windows, the browser worked without a hitch, opened quickly, and rendered pages extremely fast. If you have any experience using this browser on other platforms, let us know in the comments.
