Failed to access IPv6 only site with Firefox

I am assessing my company IPv6 readiness with Firefox. We have our internal DNS (dual stack) set up now responding with IPv6 address only for the host name of a test web server. I configured a test Windows machine (dual stack), with said DNS, and was able to ping with the test web server with host name.

Now comes Firefox. I can access my test web server with IPv6 URL (http://[a:b:c:d:e:f:g:h] kind) but when I cut and paste the host name (the one I successfully pinged with) , no, Firefox can't access it. What could be the problem that cause Firefox to not resolve that name to the proper address? Ping works fine, why doesn't Firefox?

Make sure you don't have IPv6 disabled.

See that network.dns.disableIPv6 is not set to true (from about:config).
