This list was displayed regardless of the value of the preference mailnews.headers.showReferences (that was wrong). Now, with the new message header pane, the references are not displayed at all, even if mailnews.headers.showReferences is set to "true" (this is what this bug is about). This applies also to View => Headers => All. Reproducible: Always Steps to Reproduce: 1. Set the preference mailnews.headers.showReferences to "true". 2. Select a newsgroup message which is a reply to another message in a thread. Actual Results: No references. Expected Results: The references are listed.

Confirmed.

This was fixed at some stage, I think I even reviewed the patch for it. Marking as WFM
