Polkadot JSON-RPC DevTools di Streamsphere Labs

This extension adds a new panel to Firefox DevTools that inspects JSON-RPC messages sent with Polkadot-API. It is useful when debugging applications that speak to Substrate-based chains over JSON-RPC.

Features:
- Groups multiple JSON-RPC connections per tab, so you can inspect all traffic for a page in one place.
- Provides an improved, structured JSON view for requests and responses, making complex payloads easier to read.
- Understands chainHead JSON-RPC methods so you can inspect subscriptions, operations and their lifecycle.
- Lets you follow pinned blocks and track the operations executed on each tracked block.
Decodes operations and responses into a more readable representation while keeping the underlying raw JSON available.
