IE the best browser to download other browsers !! I use Firefox as my default even though I have all major browsers Firefox, Chrome, IE and Opera and use them for different purposes and I agree that Microsoft has put effort to make the browser much better than its previous version and it is no more that slow although it lacks some functionality and extensions. Firefox has been the main browser I use since I switched from Opera but on slower network Opera is much better with its turbo technology that helps load pages faster..
