## Review summary

Window Resizer can resize the Firefox window to specific dimensions and may help test how sites render at particular resolutions. However, it suffers from reliability and usability issues: it often doesn’t work in private windows or on some Firefox versions; presets and UI behave poorly (defaults reappear, duplicates appear, and interaction is mouse-only with no clear toolbar icon); creating new sizes is error-prone; and resizing the window does not always affect the page content as some users expect. Overall, the functionality exists but is inconsistent and frustrating.

### Pros

- Resizes the Firefox window to specified dimensions (functionality observed when it works).
- Can be used to spoof website rendering by presenting a chosen window size to sites.
- Provides preset window sizes out of the box.

### Cons

- Often unusable: doesn’t work in private windows and may fail on some Firefox versions.
- UI is mouse-dependent with no visible toolbar icon or keyboard navigation.
- Presets frequently reappear after deletion and new presets can auto-add unwanted items.
- Creating new window sizes is error-prone with duplicates or deletions; defaults reappear.
- Resizing the window does not necessarily affect the page content, which may not meet some users' needs.
