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.

How much power is used by Firefox every day? What is it used for? What is the carbon footprint? Come learn how we get data on these topics, and what can we do about it!

With insights from telemetry and power profiling, the presentation will show how much power is used by various parts of Firefox, explain what we have done to reduce power use, and share ideas we have to improve further.

I'll share things we've learned while working on improving browser front-end performance. Techniques, best practices, what to definitely avoid, etc. There won't be a deep dive into any specific tool, but examples of how we measured performance and avoided / eliminated regressions during the Quantum / Photon development cycle, and what things we learned along the way.

Let's review together what happened with Firefox in 2014 and where we are headed in 2015.

Mozilla has participated in the Google Summer of Code every year since it started. This talk will review what Mozilla has gained, show off a few successful projects, and explain the great opportunities to participate for both students and mentors.

The WebRTC technologies have the potential to change how people communicate on the web. I will first give a quick overview of the building blocks behind WebRTC (getUserMedia, PeerConnection), then explain how they work, show how the APIs look, and give a demo of some possible use cases.
