Summary

Context

APZ makes scrolling responsive by pre-rendering more content than what is visible in the viewport [1]. This lets us present it asynchronously without blocking on the content thread. APZ being enabled is still conditional at runtime on e10s being enabled. APZ will be enabled for wheel input on Windows, Linux, and OS X, and also for trackpad scrolling on OS X. In future releases we plan to expand this support to other input methods including touch, keyboard, and scrollbar dragging.

Enabling the feature

Async Scrolling in e10s is available starting with Firefox 40 and it can be enabled by setting the following pref to true:

layers.async-pan-zoom.enabled

Test cases

Desktop tests will focus on: - Scroll through high-traffic sites - Scroll though a webpage while being in Fullscreen Mode - Scroll through a web page while being zoomed in or out - Scroll through a PDF document

Overview

Draft test suites:
[DONE] Regression Test Suites: [1]

-To use APZ you just need E10S, and to scroll with a mouse wheel or a trackpad/touchpad. (Arrow or page dn/up keys do not trigger APZ.)
