This would include creation of iframes, tool load and init time etc.

Timing needs to begin as early in toolbox creation as possible.
This obviously needs to use the timing API

Sounds great!

Do you plan to integrate that into DAMP?
It would be really handy to track more granular data.
Today we only track: open, close and reload.
You can see an example of data coming out of DAMP:

Having more detailed data may help finding regressions impacting a specific stage of the loading.

Yes, that is the plan.
Product: Firefox → DevTools
Severity: normal → enhancement
Priority: P2 → P3

I think DAMP in combination with event telemetry gives us a fairly accurate picture of this telemetry, closing.
