I would like to create exceptions for select third-party cookies. But, I don't know what domains the third-party cookies come from (yet). Typically this is for logins to white-labelled support sites e.g. those managed by Zendesk.
Is there any way to see what third-party cookies are being blocked on a given page?
If you visit a page in Firefox, on the left side of the address bar you find a shield icon. Clicking on that you can check what is blocked under which category (i.e. third-party cookies, different kind of trackers etc.).
Find out more in this article.
(You cannot tell, however, for an already saved third-party cookie, which site it originates from.)
