DNSSEC enabled for my domains
If you're using the DNSSEC validator and you're reading either my blog or Planet Grep, you may have noticed that the validator icon went from the gray "undefined" version to the green "validated" one. That's right, I have working DNSSEC now—with thanks to Philip for doing all the hard work.
I just installed the DNSSec extension for firefox (linux), and the icon is a question mark.
Even http://www.dnssec-validator.cz/ has the same question mark, and I would supsect if there is a site that implements it (correctly) is that one.
Any idea what can cause this, or how I can check if the extension works?

Their documentation page explains the possible results fairly well IMO, you might want to check that. If that doesn't work either, I'd say contact the developers?

That plugin does show the difference between these two cases.
