Excelent to manage requests, creating controled data scenarios between user and server.

Is source code available for this addon? The license is listed as BSD 2-clause.

Can you add a feature to send a request/response content (headers+body) to an url as POST? (In JSON by example). I want to analyse some requests of a game to save some metadatas in my web site to centralize evolutions of my team.

Very easy to use. I needed to test some feature flag behaviour when key APIs failed in a web application. My only suggestion would be to make it more evident that the add-on needs to be switched on. The button is hidden away in the corner.
