When navigating directly to a hawtio page that is NOT under dispatch, like http://127.0.0.1:8080/hawtio/logs, Firefox will display the page with just the top navigation visible. There will be no page body. Chrome behaves as expected. I believe this is a problem with hawtio and not the dispatch plugin.
