Microsoft's browser accounts for about 95% of internet usage, but it has lots of bugs and lacks many features. There is an alternative. For some time I've been using browsers from Mozilla. You may know them better as Netscape, but this is the open source version that is being very actively worked on. I have happily used their internet suite (browser, email and web design), but more recently have switched to their newer browser, Firefox. Today Firefox reached version 1.0. It's a wonderful tool with features such as pop-up blocking, tabs and an ever-expanding selection of extensions to add even more goodness. Go to their site for more details.
