Power profiling with the Firefox Profiler

by Florian Quèze Support for power profiling was recently added to the Firefox Profiler, enabling both Firefox engineers and web developers to get very precise measurements of the power consummed by running their code. After a brief introduction to the Firefox Profiler, the presentation will explain how this power profiling feature works, where the data comes from, what the limitations are on the various platforms. Interesting things that could be measured on Firefox will be shown, and some surprising profiling results will be shared.
