Overall Goal
Enable a smooth and responsive user experience for Firefox desktop and mobile users.
Justification
Competitive versus other browsers
We believe or have data that hangs, jank, and other forms of poor performance result in users moving to other browsers. [evidence needed]
Competitive versus native
"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
- 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
- Specific use cases with Top-N sites and measure frame rate
- 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
- www.facebook.com
- www.twitter.com
- www.nytimes.com
- www.latimes.com
- www.foxnews.com
- www.engadget.com
- www.tumblr.com
- www.macrumors.com
Internal Projects we care about
- Gaia Team
- Partner Engieneering
- Games/VR
- Shumway
External Projects
And a list of 5 web frameworks that are likely focal points for concerns along these lines.
Identify existing programs that have the same or similar goals
When will they land? If they land did they solve the problem?
- Firefox Content Performance program
- Async pan zoom
- Off main thread compositing
- Project Silk
- E10S
