Firefox/Content Performance Program

Overall Goal

Improve the performance of web content within the Firefox browsers.

First Priorities (Q2 2015)

Scrolling Performance

Improve the scrolling performance of Firefox on three websites: Twitter, Facebook, and Yahoo search results.

Focus on two platforms:

• A modern and popular Windows 8.1 laptop/tablet (TBD)
• The most popular Android phone (TBD)

Page Navigation Performance

Optimize the following page navigation experiences:

• Entering a search term in the Firefox Homepage -> Yahoo search results listing
• Entering a search term in the Firefox search box -> Yahoo search results listing
• Yahoo search results listing -> an individual search result

Again, focusing on the Windows 8.1 laptop/tablet and a particular Android phone.
