About this extension
Take full control of your browser's network traffic. Enhanced Network Tab is an advanced debugging and analyzing tool designed to intercept and modify HTTP requests and responses directly within Firefox.

While many extensions offer simple static redirects, Enhanced Network Tab provides true dynamic control, making it the spiritual successor to Tamper Data.

What you can do:

• Capture traffic in real-time.
• Modify every aspect of a request: URL, HTTP method, custom headers, and the request body.
• Use for mocking API responses to test frontend behavior.
• Analyze data flows for scraping or security testing.

Technical Details:

Leveraging Firefox's onBeforeRequest and onBeforeSendHeaders APIs, this extension places a blockage point in the network flow, allowing you to inspect and edit data before it leaves the browser.

If you are accustomed to tools like Burp Suite, OWASP ZAP, Fiddler, or Charles Proxy, but need a faster solution integrated directly into the browser (similar to Postman but for live traffic), this is the tool for you.
