Thanks for flagging this. Clicking the Learn more returned a not found because the placeholder was not available. I created the placeholder which is used for testing and the content will show when the cookie banner lands GA.

(For the record)
The placeholder at https://support.mozilla.org/en-US/kb/cookie-banner-reduction has no approved content. (From bug 1682551 comment 9) Users who are not signed in to Mozilla Support and signed in users with no special permission will now see a Page Not Found (404) page when they visit an article with no approved content (screenshot).. This can be an issue for in-product links when content is pending review or when the linked article is only a placeholder, as reported in bug 1786702 (quote: The opened page, https://support.mozilla.org/en-US/kb/quick-actions-firefox-search-bar?as=u&utm_source=inproduct, is a 404).

I've verified that this issue is no longer reproducible, now the correct page is opened when clicking the Learn More button from the about:preferences page. Tested using Firefox Release 127.0 (Build ID 20240606181944) on Windows 10 x64.
