How to programmatically access Firefox power consumption metrics?

Developer Community

I’m trying to measure power consumption in Firefox using automation. My goal is to get power consumption metrics for specific webpage loads.

What I’ve tried:

  1. Using Puppeteer with Firefox’s profiler:
    • Enabled power profiling preferences
    • Used the Profiler CDP commands
    • Got profile data but no power metrics

I know Firefox DevTools has power profiling capabilities in the Performance panel, but I need to access this programmatically. Is there a way to:

  1. Access the same power metrics that Firefox’s Performance panel shows?
  2. Get power consumption data through Firefox’s debugging protocol or any other API?
  3. Enable and collect power profiling data in an automated way?

Any guidance on the correct approach would be greatly appreciated!
