How to find out exactly WHICH cookies are set by a webpage?

[pstover]

Assume I visit a webpage

https://wwww.foobar.com

How can I find out which cookies are set/updated by this webpage?

Is there a cookie real-time monitoring AddOn (for v52.* and v58.*)?

Oftentiems the Cookiename is (much) different from the URL domainname.
Moreover occasionally more than one cookie ist set.

So its seems to be more difficult than at the first glance

When you are either on the web page or having left and on a blank page . . .
. . . open /Tools/Options/Privacy & Security/History/Show cookies - there should be a list with an extendable tree.
The names for the sites visited should show.
Much of this will have to do with how you have cookies set. If you are allowing third party cookies they could be from anywhere but if you have it set for the visited site only they should be easy to pick out.

This shows me ALL cookies which are set in the past.

How do I get only the cookies set´by a certain (=current) page?

Do I find this somehow in Web Developer Tools?

Not really.

Close all tabs apart from the site you want to check. Manually clear all cookies and restart Firefox. Visit the site and the only cookies then showing in the Cookie Manager will be ones derived from that site, including 3rd party ones.
