1944416 - Individual tabs from closed tab groups in closed windows cannot be restored from history menus

Status: VERIFIED FIXED

(Firefox :: Session Restore, defect, P1)

Description

[Jeremy Swinarton]

Steps to reproduce:

1. Open some "worth-saving" (i.e. not about:blank tabs). Put some (but not all — see bug1941622) into a tab group.
2. Right click the tab group label and click "delete tab group".
3. Open a new window.
4. Close the original window.
5. From the top menu, go to "History > Recently Closed Tabs". Find the closed tab group in the list. Click any of the tabs within that tab group.

Expected result:

The tab opens in the new window.

Actual result:

Nothing happens.

This is a follow-on bug from bug1932941, which allows users to reopen closed tab groups from closed windows, but not individual tabs within the tab group.
