Internet Explorer has been slow for a long time. It was great when I was a kid, but it's really gone downhill. I use Opera as my main browser. I also use Chromium. (That's an open-source version of Chrome and it's basically identical other than the color of the icon. I use Linux and you can't get Chrome on Linux.) Most people recommend Chrome or Firefox. However, I don't recommend Firefox because when you check boxes and select items from drop down menus on a page, click a link to another page, and then go back to the previous page, it's all gone. So I recommend Opera and Chrome/Chromium. My dad says that there are websites that don't work in Opera, but I've never encountered this problem.
