iRecord - anyone else getting security warnings?

When sightings have been verified on iSpot I usually post them on iRecord. But today I’ve been getting a warning:
Warning: Potential Security Risk Ahead

Firefox detected a potential security threat and did not continue to If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

What can you do about it?

The issue is most likely with the website, and there is nothing you can do to resolve it. You can notify the website’s administrator about the problem.

Is this something to take seriously?

It usually an issue with the security certificate (expired, or misconfigured). It can be a matter of not using secure HTTP. (Possibly a glitch in negotiating the protocol.) And for all the details that FireFox gives, it could be that it thinks the site has been hacked.
One of the worries is that the DNS has been hacked, and it’s directing you to the wrong site. If it’s not a site that you enter passwords or credit card details into there’s less risk, but it could still attempt to execute malicious code.
Some details from the equine’s oral orifice.

Thanks for the input - but it seems to be OK again now.
