The goal of this lab is twofold. First, to provide students with a real-world experience of working collaboratively in an open community; and second, to work on a cutting-edge, but manageable project within the Mozilla community.


To conduct A/B performance tests of the Chrome Experiments using nightly builds of both Firefox and Chrome, in order to identify performance bottlenecks in Firefox. Also, to profile and file bugs in order to fix these issues.


  • As a group determine a method for dividing the Chrome Experiments so they all get tested
  • Install both the Firefox and Chrome nightly builds
  • Test each experiment in the two browsers, looking for various issues:
    • Speed - is Firefox as fast as Chrome at rendering the graphics?
    • Smoothness - are the graphics as smooth as in Chrome? Do you notice a lot of pauses, jerkiness, etc.?
    • Responsiveness - does Firefox remain responsive while you run the demo? Is it pegging your CPU(s)?
  • Record your findings, as well as browser and computer info ([about:support], [about:]) in the Results Spreadsheet.



(humph) Let's refine this a bit more, such that we track:

Name of Experiment | URL of Experiment | Your Name | Date of Test | Hardware Info | Browser Info | Firefox Performance - Speed | Firefox Performance - Smoothness | Firefox Performance - Responsiveness | Notes and other Details |
