When you use an iframe to embed a widget, the widget does not display in firefox.

Repros on:

• Firefox 62.0.2 (64 bit mac)
• Firefox 62.0.3 (64 bit windows)

Does not repro on

• Safari 11.1.2
• IE 11.0.85 (64 bit windows)

Steps

1. Load https://jsfiddle.net/ggreer/7bk6o5gv/ in Firefox
2. Hit run button

Result

JSFiddle displays an empty iframe.

Expected Result

JSFiddle should show an iframe with the itch widget of a terrible game.

The widget loads for me on firefox. Are you sure you don't have some security settings configuring that might be blocking third party iframes or something similar?

Doh, Privacy Badger strikes again! Thanks for checking it out.
