Microsoft’s new Internet Explorer 9 saw a return to form for the companies’ web browser which for many years has received poor reviews from the tech community. Firefox 4, however, appears to have set the bar even higher, bringing in faster page loading and improved privacy and security. The browser also includes WebM video and WebGL 3D graphics and, unlike Internet Explorer 9,it is compatible with Windows XP. The new WebGL 3D will allow developers to bring more complex gaming and visualizations to the web, all of which will run within the browser.
