User Reviews

Users consistently praise the add‑on as essential for restoring closed tabs and like its toolbar list and configurable history. Repeated complaints are about reliability (button sometimes does nothing), wrong/spam pages opening instead of the chosen tab, and a UI limitation preventing one‑click restore plus dropdown list simultaneously. Reviews also note inconsistent behavior around how many tabs are kept (some cite a 25‑tab limit).
Pros
  • Provides a quick toolbar button that lists recently closed tabs for easy reopening.
  • Widely loved and considered one of the best/most useful add-ons by long‑time users.
  • Has options to configure how many closed tabs are tracked (user-adjustable).
  • Allows reopening multiple closed tabs from the list (preferred over other add-ons by some users).
Cons
  • Sometimes reopens the wrong page or even spam/ad pages instead of the selected closed tab.
  • Reliability problems: the button or restore action can fail or “not work” at times.
  • UI limitation: users report missing dropdown/triangle and inability to both restore the last tab with one click and open the list at the same time.
  • Conflicting behavior or limits on history size (some report a 25‑tab Firefox limit; others report no restriction).
