Steps to reproduce:
- Open a new Fx window ("window A").
- Open a new Fx window ("window B"). Go to
data:text/html,<body bgcolor=green>. - In Window B, open a new tab. Go to
data:text/html,<body bgcolor=darkred>. - Open a new Fx window ("window C"). Go to
data:text/html,<body bgcolor=magenta>. - In Window C, open a new tab. Go to
data:text/html,<body bgcolor=blue>. - Close window A.
- Close the
darkredtab in window B. - Close the
bluetab in window C. - Bring window B (green) back in focus. Press Ctrl+Shift+T. The
darkredtab will reappear. - Bring window C (magenta) back in focus. Press Ctrl+Shift+T.
Expected behavior: the blue tab reopens.
Actual behavior: Window A will reopen.
This is similar to, but distinct from, bug 1839093.
NONONO it's a feature!!! Check changelog!!! (Section "Changed) https://www.mozilla.org/en-US/firefox/116.0/releasenotes/
Ooooh nevermind, sorry, I just realized it is a super complicated (and probably very rare) bug you discovered. Apologies.

Yes, I'm aware of the feature. (Or I'm aware now, anyway. It did slip past me at the time.)
As an aside, though, I would also recommend reverting it, because the new behavior — as specified, I mean, not just with the bug — explicitly breaks locality in very surprising ways if you're the sort of user who uses multiple windows and multiple tabs-per-window. In particular, per bug 1833416's title, the "expected" behavior in step 9 would be to restore the blue tab first despite its window not being in focus. I would be very surprised to learn that that's what most users would actually want!
I can definitely see it being useful to have a generic global undo operation for this sort of thing (the discussion in bug 1850616 may perhaps also provide a motivating example?), but I don't think it was a good idea to subvert the existing meaning of Ctrl+Shift+T in this way.
(Also moving to Firefox :: Session Restore, where the previous bugs were; mea culpa. Though perhaps Firefox :: Keyboard Navigation would be more appropriate?)

Hi, I'm not able to reproduce. This might have been fixed by some additional bug fixes in this area (and Window A shouldn't actually ever reopen if the only tab open is new tab - there was an inconsistency that was fixed recently in bug 1847617). I'm going to close this out, but if you are seeing the same bug please reopen this (note: we do not revert features upon request, please only use this forum for actual bugs).
