Can not access embedded Google Map when Google APIs is set to use SSL

Reproduction steps:

1. Enable 'Google APIs' in the settings.
2. Go to http://www.noradsanta.org/en/index.html.

Expected: An embedded Google Map to appear.

Actual: A message box with the following text appeared: "The Google Maps API server rejected your request because you do not have permission to use this service over SSL."

Note: I'm using HTTPS-Everywhere 0.9.2 on Firefox 3.6.13, but I don't know how to choose that from the version selector.
