In order to improve their products and provide better features and
performance, Google announced it will no longer support older browsers
on the Google Docs Suite and the Google Sites Editor.
They plan to phase out support on March 1, 2010. Google will continue to support Internet Explorer 7.0 and above, Firefox 3.0 and above, Google Chrome 4.0 and above, and Safari 3.0 and above.
Assist Technology will follow their lead and not support the older browsers.
