Problem

When I try to login in the Structure macro on a Confluence page, the authentication doesn't work, and nothing happens.

Solution

This happens when Firefox settings block all third-party cookies, making it impossible for the Structure macro to authenticate.

An alternative that can work is to add Confluence itself: https://confluenceURL to the exceptions list on the Manage Exceptions page.
Note: with this exception, other apps and embedded content may also be able to use third-party cookies.

If you’re currently intentionally blocking third-party cookies, we recommend reviewing the proposed change and evaluating whether it can work for you first. If it doesn’t, the only solution is to use a different browser that doesn’t have the same restriction settings.
