AMO registration not working - captcha function

I just tried to register on AMO, in order to report in a review that an add-on offered is apparently defunct.

The captcha function on the registration form is not working: no text to be copied appears, and the hyperlinks to a different text and a different form of check are defective.

What now?

Are you using NoScript, Request Policy or similar add-ons and which are blocking requests to google.com from addons.mozilla.org?

Can you please try in safe-mode or with a new profile of Firefox?

I just tried in a fresh profile and it works just fine for me.
