== Overall Goal ==
Enable a smooth and responsive user experience for Firefox desktop and mobile users.
== Justification ==
We believe or have data the hangs, jank, and other forms of poor performance result in users moving to other browsers. [evidence needed]
"Both aspects here are important. Making existing content less janky
makes it easier to compete against other browsers. Making it easier to
create jank-free content makes it easier for the web to compete
against native." - jonas
=== Implementation Strategy ===
==== Outstanding Issues ====
* How do we work with [[Firefox/Content_Performance_Program | Firefox Content Performance program]]
* What forms of jank are we prioritizing?
* What are our use cases, projects, sites that we prioritize
* How do we measure? How do we automate that measure and see our progress over time?
==== How do we measure ====
* Video (compositing on-time).
* Animations (compositing on-time, JavaScript/main thread latency+throughput)
* WebGL/WebVR (compositing on-time, input latency, main thread latency, and JavaScript throughput).
* Scrolling (compositing on-time, input latency, and layout/painting).
==== Sites we care about ====
Important sites, especially those perform worse in Firefox versus Chrome/Safari/IE. Perhaps measu
