 18// Although it's generally better web development practice not to use
 19// browser-detection (feature detection is better), the subtle browser
 20// differences that Selenium has to work around seem to make it
 21// necessary. Maybe as we learn more about what we need, we can do this in
 22// a more "feature-centric" rather than "browser-centric" way.
