Update: Video should now be working for Firefox and Opera browsers, as long as you have Flash installed.
We are working on adding a complete library of videos in "WebM" format, so that Firefox and Opera users can watch our videos without requiring that Flash be installed. In the meantime, please either install Adobe Flash, or use Internet Explorer, Microsoft Edge, Google Chrome or Apple Safari as your browser.
