So below are the domains to test: - ​assets.adobedtm.com - ​www.googletagmanager.com - ​www.googletagservices.com - ​connect.facebook.net - ​www.facebook.com - ​ib.adnxs.com - ​adserver-us.adtech.advertising.com - ​bid.contextweb.com - ​fastlane.rubiconproject.com - ​js-agent.newrelic.com - ​bh.contextweb.com I opened the URL in a fresh browser profile (Firefox Nightly 64, uMatrix installed, normal mode) and loaded the page. The video doesn't play. I disabled the Spoof Referrer option in uMatrix and then WHITELISTED: - facebook.com (including all related domains) - facebook.net (including all related domains) - fbcdn.net (including all related domains) and the video played. The other resources didn't help. So in conclusion: - facebook.com is in Disconnect list = [tp-social]

Added uMatrix results.
