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.

OS: macOS → All
Hardware: x86_64 → All
Whiteboard: [necko-triaged][necko-priority-next]

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.
