The ArticleFeedback user-agent verification fails with the recently released Firefox 20 Beta, as the ua.indexOf( 'firefox/2') also matches the Firefox/20 user-agent. Therefore Firefox 20 users just see the browser not supported message. This Firefox version will release on 2. April, so a fix should be deployed prior to this date.
