Bugbug thinks this bug should belong to this component, but please revert this change in case of error.

When I change my default setting to allow autoplay of audio and video, the video on this site still does not play. I think this isn't related to block autoplay; the video simply cannot be played for some other reason.

If I disable enhanced tracking protection, privacy badger, and uBlock origin, the video plays. Enabling enhanced tracking protection by itself prevents the video from playing.

I have reported this problem via the enhanced tracking protection UI (described here: https://support.mozilla.org/en-US/kb/enhanced-tracking-protection-firefox-desktop). I am not sure where that report will land, however.

Looks like this is caused by ETP Strict mode.

I see these in the console:
Error: Script error
http://requirejs.org/docs/errors.html#scripterror require-2.1.2.js:7:926
VideoManager.initialize() did not receive a valid error callback function. CBSI-PLAYER.js:9:740798
The script that is failing to load which breaks the video is https://s0.2mdn.net/instream/html5/ima3.js. Shimming it with a blank script like in bug 1487373 works, so this is effectively a dupe of that bug.

I was able to get this working with a fleshed-out shim for Google IMA (ima3.js), and a revised Google Publisher Tags shim.
