User reviews
Pros
- Effectively restores recently closed tabs and windows.
- Lightweight, only uses RAM when opening the popup.
- Simple and clean interface without unnecessary extra buttons.
- Allows choosing which closed tab to reopen from a list.
- Has been reliable for long-term users before recent issues.
Cons
- Icon and background do not adapt well to different themes, especially dark mode.
- Usability concerns: users want a single left-click to reopen last closed tab and a double-click to show the list.
- Design issues such as large spacing between menu items and wide gaps between favicon and title.
- Functionality issues in recent versions, like not closing the popup after restoring a tab or reopening in different windows than originally closed.
- Some users report the add-on opens wrong or previously closed tabs instead of the selected one.

Extension safety
Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk
impact extension cannot do much harms, whereas a high risk impact extension can do a lot of
damage like stealing your password, bypassing your security settings, and accessing your
personal data. High risk impact extensions are not necessarily malicious. However, if they
do turn malicious, they can be very harmful.
Undo Closed Tabs Button requires a few sensitive permissions. Exercise caution before installing.
Risk impact analysis details

Firefox Browser Add-ons, the amount of time the Firefox add-on has been
around, and other signals about the

as we discover new ways to detect malicious extensions. We recommend that you always
exercise caution when installing a Firefox add-on.
