Optimal Browsers

This site supports these web browsers and their newer versions:

  • Firefox 3.6
  • Google Chrome
  • Internet Explorer 9
  • Safari 5
  • Opera 11.6

This site has been tested in the latest stable release of Firefox, Internet Explorer, Safari, Opera, and Chrome. We employ several CSS and JavaScript libraries which claim support for older browsers such as Firefox 2.X and IE 6 and generally write standards-compliant and accessible HTML and CSS.

While we do our best to support older browsers, things aren't always perfect. Older browsers may render content slowly or have other unintended problems due to their age and/or relative lack of support for web standards and emerging web technologies of the last few years. If you are not using one of the optimal browsers we strongly advise that you upgrade/switch if possible. Internet Explorer 6 users who are unable to upgrade due to workstation restrictions may wish to consider Google's Chrome Frame Plugin for Internet Explorer, which claims a faster and better web browsing experience.
