URL: http://podcast.ft.com/s/ft-alphachat/
Browser / Version: Firefox 53.0
Operating System: Windows 7
Problem type: Something else - I'll add details below

Steps to Reproduce

1. Navigate to: http://podcast.ft.com/s/ft-alphachat/
2. …

Expected Behavior: There should be a podcast underneath every post.

Actual Behavior: The audio-play button for the podcast is not there. The same website works fine in Chrome (see picture).

The podcasts used to work fine in Firefox... and the podcast button stopped showing up a few weeks ago.
