The second most popular web browser in the world, Firefox, is a beautiful, but heavy machine. Its biggest attraction are tabs, flexible bookmarks and RSS management, and extensions. However for people who are still using systems with no abundance of main memory it can be a pain intensively using Firefox throughout a day or longer. It is just that memory hungry. So some people have been looking at alternatives such as Epiphany, Galeon, Konqueror, or even the lightest but arguably ugliest and least featureful among them, Dillo. But as it usually happens, out of nowhere comes another alternative, one which may be hitting the right balance that many people are looking for. It is NGLayout (Gecko)-based Kazehakase (made by Japanese developers).
Its aim is to be lightweight (small memory footprint) and yet modern, user friendly, fully functional and innovative at that. And in its early releases it seems to be accomplishing just that.
