Apollo Client Devtools is a powerful Firefox add-on designed for developers using Apollo Client, the popular open-source GraphQL client. It enhances your development workflow by providing four key features: a built-in GraphQL explorer to run queries seamlessly via your app's network interface, a query watcher to monitor active queries and their variables, a mutation inspector to track all mutations affecting your application data, and a cache inspector featuring a tree-like interface for exploring and searching Apollo Client's cache data. This tool simplifies debugging and helps you maintain efficient GraphQL operations within your applications.

You can access the source code on GitHub and report any issues directly through the project's issue tracker.

Well, it just doesnt work on LinuxMint Firefox. Just keeps on trying to connect. Of course I have provided the flag in my client config. Doesnt work on Chromium browsers either. Thanks for wasting my time. Apollo is great, this extension sucks.
