Click the selector from the top right part of the page and select the "content" process. 4. Focus the search field from the top-right part of the page. 5. Write the "TIME_TO_LOAD_EVENT_START_MS" string and the observe the behavior. [Expected result]: - The "TIME_TO_LOAD_EVENT_START_MS" histogram is displayed. [Actual result]: - The "Sorry! There are no results in Histograms for “TIME_TO_LOAD_EVENT_START_MS”" message is displayed.

I can reproduce independently of the network.http.tailing.enabled preference value. This is not a networking bug.

This is as expected as TIME_TO_LOAD_EVENT_START_MS expires in version 60[1]. All of the other mentioned probes are also expired in 60. Nightly is at 60, so the probes have expired (ie, are not recording).

It sounds as though these probes continue to be useful and used. Please bump the expiry five versions and request Data Collection Review, and we'll get them recording again in a jiffy. If these probes will be useful indefinitely, you'll need to make a case for non-expiry, include some automated tests for them, set them to "expires_in_version": "never", and then request Data Collection Review.
