3. **Content Script Analysis**: Examines how extensions interact with web pages
4. **Manifest Analysis**: Reviews extension manifest settings for security best practices
5. **Combined Risk Assessment**: Calculates overall risk based on multiple security factors

Risk Rating Methodology

**Critical**: Highly sensitive permissions or combinations that could be dangerous if misused
**High**: Permissions that could potentially be used maliciously
**Medium**: Permissions that require caution as they provide significant capabilities
**Low**: Permissions with limited potential for misuse

`management`: To access information about installed extensions
`tabs`: To display the analysis interface

The extension runs entirely in your browser and does not:
