Key Features of Network Inspector:​

When you use Network Inspector, you gain access to a suite of powerful features:

• Real-Time Monitoring: Instantly capture and display network requests as they happen. This feature ensures you're always aware of your web pages' activity, providing detailed insights into how they load and interact with servers.
• Detailed Request Information: View comprehensive details about each network request, including the URL, status code, method, size, and duration. This detailed information helps you pinpoint issues and optimise performance.
• File Type Categorization: Automatically categorise requests by file type (JS, CSS, HTML, images, fonts, videos, audio, JSON, XHR, and others). Each file type is colour-coded for easy identification, ensuring a clear and organised view of your network traffic.
• Filtering and Sorting: To focus on what's important to you, filter requests by local and third-party resources or by specific file types. Sort requests by URL, status code, size, method, and duration to quickly find the data you need.
• CSV Export: Export your network data to CSV for further analysis and reporting. This feature makes it easy to share insights and collaborate with your team.
• Tooltips for Headers: Hover over headers to view detailed information about request headers, helping you understand the specifics of each request.

Chrome Permissions:​

To provide these robust features, Network Inspector requires certain permissions in Chrome. Here's why each permission is needed:

• Host Permission: This allows the extension to monitor and analyse network requests on the websites you visit. It's essential for capturing network activity and providing you with detailed insights.
• Tabs Permission: Needed to identify the active tab and ensure that network requests specific to that tab are monitored. This permission helps in providing accurate data relevant to your current browsing session.
• WebRequest Permission: This is crucial for intercepting and analysing network requests. It enables the extension to gather detailed information such as URL, method, status, headers, and response data, which is vital for debugging and optimisation.
• Storage Permission: The Network Inspector extension uses local storage to temporarily save network request data. This ensures that you can continue to view and analyse network requests even after navigating to a different tab or reloading the page.
• No Remote Code Execution: Network Inspector does not execute any remote code. All code runs locally within the extension package to ensure security and integrity.

Note: After adding the extension, you may need to toggle it in the extension settings page to make it visible in your browser's extension section.
