Google's ReCAPTCHA Stalls

Site is an example, but problem occurs on all sites using ReCAPTCHA.

When the user clicks on the widget, it responds with a spinning animation, but never proceeds to the Success or Additional Verification (like image identification) steps, it just resets to the initial state. Problem occurs in Adblock Browser even when all adblocking is disabled. Problem does not occur when using Safari+ABP.

I had an issue with ReCAPTCHA several weeks ago and found the solution on the BeepingComputer forum. I had to remove all add-ons (in Firefox) and reinstall the Adblock Browser. It worked.
Have you managed to solve this?
