Profiler not working in web app

[ssnepenthe]

Sorry if this isn't the appropriate place to report, but I'm not totally clear on where development takes place for the various parts of Clockwork.

This has been tested in FF 61.0.2 as well as FF dev edition 62.0b16.

In the extension view, the profiler seems to be working fine (awesome, by the way - thanks for the update).

However in the web app view if I select a request with profiler data, click "performance" and then "profiler" it just hangs at the "Profile is not present for current request" screen. It doesn't even appear to be triggering the request for the "extended" API endpoint.
