Details

I have encountered few negative firstPaint values when analyzing telemetry submissions from Release (about one every 20000 submissions). Irving, do you have by chance an idea of why that might happen?

For firstPaint I don't have any specific ideas; those values are recorded by StartupTimeline (http://dxr.mozilla.org/mozilla-central/source/toolkit/components/startup/StartupTimeline.h#15), so the next step would be to check if those values are reported by subtracting two time stamps, and whether those time stamps are affected by system clock adjustments (JS Date.now() is, for example).
