What Browser Am I Using?

This site is composed to deliver many benefits when viewed with a newer browser. You will realize the best experience with a browser such as Firefox 17+, Internet Explorer 9+, Opera 12+, Safari 5+, or Google Chrome. Newer browsers such as these can display webpages with greater faithfulness to recent web standards. Older browsers do not understand, and cannot correctly display, pages composed according to newer standards.

Most browsers are free to download, install, and use on your computer. Having one browser installed on your computer, such as Internet Explorer 8, does not preclude installation of an additional browser, such as Firefox. As an added bonus, not only do newer browsers do a better job displaying web pages, newer browsers let you browse the web more safely.
