1923894 - Add navstart to request start timing to the pageload event

Status: RESOLVED FIXED

(Core :: Performance Engineering, enhancement, P3)

Description

[Andrew Creskey [:acreskey]]

It would be useful to collect "navigation start" to "request start" in the pageload event as we've observed that this timing is very sensitive to changes in the runtime.

Necko team is looking at rolling out DoH on Android in late 2024 and since we already store the TRR domain, this could be a good view on the impact on "time to first byte sent."

If folks have any reservations, let me know, otherwise planning on adding this next week or so.
