If you want to manage open browser windows without using tabs, Net.Ex Pro may be the way you want to go.
This free browser offers a nicely designed interface organized a bit differently than Internet Explorer or Firefox. While it still offers an array of buttons on a toolbar, the appearance is fresh. Mastering its differences requires only a few minutes because Net.Ex Pro launches with an online tutorial that demonstrates its main features.
This app performed quickly in all of our tests. We liked how searches provided options from each of the multiple search engines simultaneously. New windows opened when we clicked links and cascaded, and the site-management pane (which listed open pages in a directory tree format) made navigating among windows very simple. Configuring the browser to handle pop-ups, blacklisted URLs, and history was very easy. Longtime surfers and novices alike will want to try out this browser.
