Add Telemetry for first meaningful paint
We have the SIMPLE_MEASURES_FIRSTPAINT probe which has seen glorious drops due to bug 1447719 having landed and enabled the "blank window" startup perceived performance fix. However, measuring how long until we get to the browser UI is still probably important. We should try to measure that. : https://mzl.la/2uqOQN7

Is SIMPLE_MEASURES_DELAYEDSTARTUPSTARTED covering what you want? I'm not sure why it drops so nicely in the last few days, I didn't expect to affect it.
The last couple of days shouldn't be trusted as we have less submissions than usual. As submissions for these days accumulate I expect the improvement will disappear. It certainly doesn't correlate with the landing of bug 1447719 on March 22nd.
Priority: -- → P3
(Setting a priority to get this out of my triage list, feel free to modify it to align with the goals of the perceived performance team)
Actually, yes, SIMPLE_MEASURES_DELAYEDSTARTUPSTARTED seems like a fine probe for this. Thanks. :)

Can we rename it to something more expected?
