## Review summary

Users appreciate QR Code Util for its clean interface, usefulness, stability, and speed. However, recurring issues include the add-on hijacking the cmd+Q shortcut on macOS without fixes distributed, limited QR code recognition accuracy, a small and sometimes misleading text box area, lack of desired features like resizing QR images and clipboard copy, and visibility problems in dark theme. Overall, it's considered practical but could benefit from updates and improvements.

### Pros

- Clean and simple interface, considered one of the cleanest on Firefox.
- Useful and stable; it does what it's supposed to do effectively.
- Fast in generating and recognizing QR codes.
- Most practical and helpful QR code tool available to some users.

### Cons

- Hijacks the cmd+Q shortcut on macOS and the fix hasn't been updated in years.
- Limited QR code recognition accuracy especially with complex codes or certain websites.
- Text box for QR code content is too small and needs to be multi-line or better designed.
- Lack of features such as adjusting QR code image size and copying decoded content to clipboard.
- Some UI elements, like icons, are hard to see in dark mode.
