The following Firefox probes will expire in the next major Firefox nightly release: version 120 [1].

HTTP_PRELOAD_IMAGE_STARTREQUEST_DELAY

What to do about this:

1. If one, some, or all of the metrics are no longer needed, please remove them from their definitions files (Histograms.json, Scalars.yaml, Events.yaml).
2. If one, some, or all of the metrics are still required, please submit a Data Collection Review [2] and patch to extend their expiry. There is a shorter form for data collection renewal [3].

If you have any problems, please ask for help on the #data-help Slack channel or the #telemetry Matrix room at https://chat.mozilla.org/#/room/#telemetry:mozilla.org. We'll give you a hand.

It looks like we're going to remove this one since we are changing our approach (and it's a bit messy in the codebase).

We are working on an alternative approach to improving OnStart/OnStop request timing, and so will remove this probe because it's no longer as relevant and the implementation touchs many classes and methods.
