The video did not load. I disabled the Spoof Referrer option in uMatrix and then *WHITELISTED*: -2mdn.net -akamaized.net -cbsinteractive.com -vidtech.cbsinteractive.com -cbsistatic.com -evidon.com -imasdk.googleapis.com After this, the video played. The other resources didn't help. http://prntscr.com/kon1y2 -2mdn.net can be found in the disconnect-blacklist.json, disconnect-entitylist.json and disconnect_mapping.py. -akamaized.net can not be found in any of the lists. -cbsinteractive.com can be found in the disconnect-blacklist.json and disconnect-entitylist.json. -vidtech.cbsinteractive.com can not be found in any of the lists. -cbsistatic.com can not be found in any of the lists. -evidon.com can be found in the disconnect-blacklist.json and disconnect-entitylist.json. -imasdk.googleapis.com can be found in the disconnect-blacklist.json and disconnect-entitylist.json.
