Firefox CPU measurement to pageSummaryMetrics

[jannekalliola]

It seems that Firefox CPU energy consumption measurement cannot be selected to pageSummaryMetrics, or at least I didn't find the right option from the docs.

The problem I've had with the metrics and why I haven't added it everywhere is that for me when I run it locally it's very unstable? Is that something you also seen?

We have received quite stable numbers when measuring the same site several times. It depends heavily on the content, and thus all sites with ads or autostarting videos produce more variable results.
