Map embedded with iFrame in MediaWiki blocked by ArcGIS

I have a wiki ( which has a ArcGIS map created in ArcGISOnline embedded via iframe. The iframe is at the bottom of the main page linked above.

It worked happily until about November last year, but now it returns the following error:

"Firefox Can’t Open This Page

To protect your security, will not allow Firefox to display the page if another site has embedded it. To see this page, you need to open it in a new window."

The same thing happens in Chrome and Safari.

The link from the error message to open the map in a new page opens the map correctly, but only if the viewer is signed in to ArcGIS.

The map is set to share publicly.

I have considered embedding it using the HTML option, but this is trickier in MediaWiki and also the options in this do not seem to allow the timeline animation to be shown (I do like the fact that it has a simpler legend).

Any help appreciated.
