> Convenience shouldn't come at the cost of your data privacy & security.

Extension Auditor is a Opera Browser add-on that helps users understand and evaluate the security implications of their installed browser extensions. It provides real-time security analysis and risk assessment of extensions based on their permissions, capabilities, and potential security impacts.

## Features

- **Real-time Security Analysis**: Instantly analyzes installed extensions for security considerations
- **Risk Classification**: Categorizes findings into Critical, High, Medium, and Low severity levels
- **Permission Analysis**: Detailed explanation of each extension's permissions and their security implications
- **Host Access Analysis**: Identifies extensions with broad host permissions or access to sensitive domains
- **Comprehensive Report**: Generates detailed security reports with specific findings and potential risks
- **Privacy Focus**: Runs locally in your browser with minimal required permissions

## Who Can Benefit?

- Everyday Internet Users: Stay informed and secure.
- Content Creators: Vet extensions before promoting them to your audience.
- Cybersecurity Professionals: Can use this is a great starting point for pentesting browser extensions to guide deeper dynamic and runtime analysis.
- Privacy Professionals: It will be a a great help for privacy professionals to discern privacy concerns of using an extension, and compare advertised privacy practices vs actual use.

## How It Works

Extension Auditor analyzes extensions based on several factors:

1. **Permission Analysis**: Evaluates the permissions requested by extensions and their potential security implications
2. **Host Access**: Identifies broad host permissions that could pose privacy risks
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

## Privacy

Extension Auditor requires only two permissions:

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

The extension runs entirely in your browser and does not:

- Collect any personal data
- Send data to external servers
- Modify any other extensions
- Modify webpage content
