The issue is related to `Comments` breakage.

So below are the domains to test: - www.googletagmanager.com - www.googletagservices.com - ib.adnxs.com - fastlane.rubiconproject.com - connect.facebook.net - sb.scorecardresearch.com - pixel.rubiconproject.com I opened the URL in a fresh browser profile (Firefox Nightly 64, uMatrix installed, normal mode) and loaded the page. The Facebook comments area is not displayed. I disabled the Spoof Referrer option in uMatrix and then WHITELISTED: - facebook.net (including all related domains) - facebook.com (including all related domains and frames) and Facebook comments area is loaded. The daily articles section is still missing, so I WHITELISTED: - fbcdn.net (including all related domains) - appledaily.com.tw (including all related domains) and the section are loaded. The other resources didn't help. So in conclusion: - facebook.com is in Disconnect list = [tp-social] - appledaily.com.tw is not listed

Added uMatrix results.
