    1. Tracking Protection Basic enabled.
[Steps to Reproduce:]
    1. Navigate to!2018/08/06/mighty-ducks-goalie-shaun-weiss-arrested-mug-shot/
    2. Observe the page
[Expected Behavior:]
The page’s content is loaded. 
[Actual Behavior:]
Page is black.

1. Also reproducible on mobile.
This is related to `tracking protection` breakage.

Looking at the devtools console, here are the blocked resources:
The resource at “” was blocked because tracking protection is enabled.
The resource at “” was blocked because tracking protection is enabled.
The resource at “;ord=1533627989734?” was blocked because tracking protection is enabled.

So there were domains to test:

I opened the URL in a fresh browser profile (Firefox Nightly 63, uMatrix installed, normal mode) and loaded the page. The page is black.

I disabled the Spoof Referrer option in uMatrix and then WHITELISTED:
and the page content loaded with the exception of the YouTube embedded video.

This part is related to `tpvideo` breakage (

To make the video player be displayed and to play the video, I whitelisted: 
- (and all related domains) 
- (and all related domains)
The other resources (, didn't help. 

So in conclusion:
- – Advertising = [tp-ads]
- - Content = [tp-content]
- - Content = [tp-content]
- - not listed in Blacklist or Google mapping, but shows as a Google Resource in Entitylist.
User Story: (updated)

Aside from instagram embedded videos not appearing in strict mode (just a link in their stead), the page seems to be working fine (including other videos). The instagram issue is bug 1609867, so I'll close this as a dupe.
