A Week in the Life of a Browser – Refreshed

Christopher Jung

The Latest Study

Today, we are excited to announce the imminent release of our next Test Pilot study, A Week in the Life of a Browser v2. This study is an update to the original Week in the Life of a Browser study, and adds some very important metrics, including memory usage over time and browser startup speed.

The Week in the Life of a Browser v2 Study will run from October 2010 to October 2011, collecting data on the browser’s basic performance for one week, once every month. The goal is to explore the general trends of browser usage over time, which can help us design a better browser. In addition to memory usage and startup speed, the study will collect data regarding: session restore, browser startups/shutdowns/restarts, active/idle sessions, plugin and extension versions, age and size of profiles, private browsing time, and download and bookmark activities (NO content will be collected).

Privacy

Security and privacy are priorities for Mozilla, especially when dealing with user data. Test Pilot privacy settings give users control over their data – these privacy settings include:

  • Participants’ data will be transmitted to Mozilla only when they take all of the following actions:
    * Join the Firefox 4 Beta program by downloading the beta with the Feedback Add-On.
    * Submit data when the test is finished. Participants will be able to review all data before choosing whether or not to submit it.

  • Test data will be stored anonymously and in aggregate. None of it will be publicly associated with any personally identifiable information.
  • Participants can quit a Test Pilot study before they submit any test data.
  • Participants can opt-out from all user studies or disable the Feedback Add-On itself at any time. Learn more.
