I'm sharing Enhanced Network Tab, a Firefox extension I've been working on for web developers and security professionals.
The extension provides real-time capture and modification of HTTP/HTTPS traffic directly within Firefox DevTools. It's designed for scenarios where you need granular control over browser requests - whether for debugging complex applications, security testing, or API development.
Core capabilities:
Request and response interception with live editing
Request repeater for testing modified payloads
Configurable filtering by HTTP method, URL patterns, and file types
Export functionality to cURL format
Full theme support for different working environments
Privacy was a primary consideration throughout development. The extension operates entirely offline with no external data transmission, analytics, or telemetry. All captured data remains local to your browser.
The codebase is written in vanilla JavaScript using Firefox WebExtensions API and released under MIT license. I built this to address gaps I encountered in existing browser tooling, particularly around request modification workflows.
The project welcomes contributions and feedback from the community. If you work with browser-based debugging or security testing, I'd be interested in hearing how it fits your workflow.
