Attempting to play videos on Facebook always fails. Checking web console shows the error "Cross-Origin request blocked" and that the "CORS header is missing". This occurs in safe-mode or even after a refresh. I have another computer configured identically that does not have this issue.

I've also set the security "same origin" flag to false.

Please help!

Try to enable third-party cookies temporarily to see if that has effect. If that works then you need to create a cookie Allow or Allow for Session exception for involved third-party domains (possibly the domain of the player that is used). You can check in the Storage Inspector for what domains third-party cookies are created when you visit the website.

Make sure to prefix the domain with the correct protocol (https:// or http://) to make the exception work.
