While working on Firefox Translations, I have been building some experimental Taskcluster Tools for use with training.

One of the tools that would probably be useful to a general Taskcluster audience is integration with the Firefox Profiler.

I have this built as the Task Profiler. It takes a Task ID or a Task Group ID, grabs the information from the Taskcluster API, and converts it into the profiler format. From there it opens a new window and uses window.postMessage to inject it into the profiler UI.
