Description

Adds RequestFox to Browser Extensions.

Why it belongs: it is a developer workflow tool that runs in the browser, like Requestly and the React and Redux DevTools already listed. It records the API calls a page makes while you test and flags failed, slow and duplicate ones. Free to use, no account, nothing leaves the browser; the source code is not public.
