User Reviews

Users praise Merge Windows for reliably and quickly merging windows; it’s simple and practical and many think it should be built into Firefox. The main issues are poor discoverability (the feature is tucked into the tab right‑click menu with no toolbar/button) and a lack of clear instructions, which causes users to struggle to find and run it.

Pros

Performs its core task reliably — merges windows quickly and “works as advertised.”
Simple and easy to use; multiple users describe it as fast and practical.
Useful for cleaning up after long research sessions and consolidating windows/tabs.
Several reviewers feel this functionality should be built into Firefox (highly desired feature).

Cons

Discoverability: the merge action is hidden in the tab right‑click context menu with no obvious toolbar button or menu entry, causing confusion.
Lacks clear instructions/documentation — several users said they struggled to find how to run the add‑on.

Is Merge Windows Safe?

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.

Merge Windows requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details

Critical Grants access to browser tabs, which can be used to track user browsing habits and history, presenting a privacy concern.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Merge Windows has earned a fairly good reputation and likely can be trusted.
