## Description

**gRPC-Web Developer Tools** is a powerful Firefox DevTools extension designed for developers working with the official gRPC-Web library. It simplifies debugging by allowing you to inspect gRPC client network requests directly within Firefox Developer Tools. Unlike standard network tabs, this tool specifically filters and logs gRPC-Web requests, displaying them as deserialized JSON objects instead of cumbersome base64 encoded binaries.

Once installed, a dedicated *gRPC-Web* tab appears in the Developer Tools interface. This tab records your application's gRPC requests and responses, providing clear, readable views of requests, responses, and any error objects returned by the gRPC server. This makes diagnosing issues and understanding application behavior much more straightforward and efficient for web developers working with gRPC technologies.
