I am new to the WordPress world, please bare with me.

On my website have embedded some YouTube videos using the video block. I am seeing this error in the console:

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://googleads.g.doubleclick.net/pagead/id. (Reason: CORS request did not succeed). Status code: (null).

I have enabled the CORS header in .htaccess as followed.

<IfModule mod_headers.c>
     Header set Access-Control-Allow-Origin *

Why do is still see an error?

Thanks kocjs

I have found out that i have enabled tracking protection in that particular Firefox profile. A relevant warning, which i oversaw by just displaying the errors, was also displayed.

The resource at “https://googleads.g.doubleclick.net/pagead/id” was blocked because content blocking is enabled.

Apparently https://googleads.g.doubleclick.net/pagead/id. does honor the tracking protection setting.

Today i learned to use a clean browser profile to debug my website...
