business.facebook.com CORS problem when extension is enabled

When accessing to business.facebook.com the extension modifies from

origin: https://business.facebook.com
to
origin: https://www.facebook.com

then, the response of any static CDN content from facebook (CSS, JS, Images, fonts, etc) as https://static.xx.fbcdn.net/rsrc.php/v3/y8/l/0,cross/EQv5aYECiqw.css?_nc_x=ZKcX50vtxt9

responses with

access-control-allow-origin: https://www.facebook.com

but, as the URL is https://business.facebook.com the content is not loaded with error:

CORS error: AllowOriginMismatch

When extension is disabled

requests is
origin: https://business.facebook.com

And the response from Facebook CDN is:

access-control-allow-origin: *

Then the content is loaded.

Please, do not modify headers request when accessing URL != https://www.facebook.com as https://business.facebook.com

Download from Comment?

Hi,
Trying to download a video that was published in the comment section of a Facebook thread but can't see how to do this. It will only download the original posting video.

Can this be used to download a video from a comment?
