This August 27th, will mark the 3 years since Internet Explorer 6.0 was made available to the public. By internet standards, that is a very long time. Since then, Internet Explorer has gone through one service pack, and a zillion security fixes, and no feature updates/additions. The best thing to happen to the browser is the Google toolbar courtesy of Google.
By contrast, Mozilla Firefox isn’t even that old (came out in late 2002), yet it has gone through changes rapidly, adding features that far exceed Internet Explorer’s capabilities, and has been the most secure browser to surf the web on. Since using Firefox, I’ve seen zero popup ads, and zero adwares injected into my system. It also has full support for web standards, which IE doesn’t, thus showing you the web the way it’s meant to be seen.
