This browser is one of the fastest I've ever used (only Opera with all options and rendering on was faster). The plugins give it support for mouse gestures, radial context menus, advanced tabbed browsing, skinning, customized toolbars (including a non-spyware google bar!!!) and a slashdot news ticker (yesssss!). I have never been impressed by a browser like I have with this one. The best part is that it renders pages perfectly and beautifully. It allows you to just download the plugin support that you want and lets you ignore the rest of them.
While Mozilla is really an overweight piece of poo most of the time, this browser is the neatest thing since sliced bread. I would highly recommend that all of you guys -- linux and windows users alike -- give it a look.
