## Description

Merge Windows is a handy Chrome extension designed to streamline your browsing experience by merging tabs from multiple windows into a single window. It intelligently merges only windows of the same type, ensuring private windows remain separate from normal ones for your privacy. The extension avoids clutter by only showing its context menu option when there is more than one window available to merge. This tool is perfect for users looking to better organize their browser tabs and reduce window clutter effortlessly.

## Review summary

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.
