## Review summary

Users appreciate this Firefox add-on for its comprehensive and customizable form-filling capabilities, realistic data generation, and time-saving features. Its ease of use and extensibility make it popular among developers. However, multiple users report high resource usage impacting browser performance, limited support for non-standard input fields, and the absence of an auto-fill feature. Some also note concerns about example data used in documentation and minor usability challenges. Overall, it is regarded as a powerful tool for form testing, particularly with basic HTML inputs.

### Pros

- Feature-rich with support for many data types and locales.
- User-friendly interface with useful shortcuts for autofilling entire forms.
- Extensible via JavaScript to customize data generation logic.
- Runs locally, providing privacy and control over data generation.

### Cons

- Consumes significant system resources in some cases, causing browser slowdowns.
- Does not work with WYSIWYG editors or certain JavaScript-based input fields.
- Lacks auto-fill option for full automation, requiring manual triggers.
- Uses some inappropriate example data (e.g., controversial numbers) in documentation.
- Learning curve due to manual locale switching and input detection limitations.
