User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:23.0) Gecko/20100101 Firefox/23.0 (Beta/Release) Build ID: 20130814063812 Steps to reproduce: 1. Configure an A record with a low TTL say 60 seconds 2. Visit the url 3. Change the A record to point to another IP 4. Wait longer than the TTL and refresh the page Actual results: Firefox/Seamonkey queries the site on the original IP address. Closing and reopening the browser resolve the issue. Tested in Firefox 23.0.1 and Seamonkey 2.20 Expected results: Firefox/Seamonkey should query the new IP address.
you can workaround with a ctrl-shift-reload
