(P0) Stability and Performance


Performance and Responsiveness

Goals Related to Competitive Browsers

  • Raw Start: To be within 200MS of the Stock Browser for

[See Video]

  • Warm Start with Page Load: We need to be within an acceptable range with Stock and faster than Opera

[See Video]

  • Scrolling Panning, Zooming, and Frame Rate should meet or exceed customer expectations when compared to other mobile browsers

[See Video]

  • XUL Beta vs. Java: What will users see?

[See Video]

Compared to XUL: Where are we Better, Where are we worse?

  • Better: We use less memory, we now have async panning & zooming, faster frame rate, sync now runs in the background,
  • Worse: Checkerboarding, Closing tabs, Loading multiple pages at the same time, possibly tab restore
  • Worse: What are we doing about it and when?

Checkerboarding and responsiveness changes in flight, targeted to land prior to beta: https://wiki.mozilla.org/Mobile/Notes/25-Jan-2012

Other Top Issues and Their Status


  • What we need to uplift to aurora:
  • Sync stability is more about data loss
  • Sync Team would prefer to support bookmarks and history without data loss than overextend and support Passwords
    • wesj is a hero, but...
  • Q1: Protecting data for the features we have and UI [correct crypto, stability]
  • Really trying for Password Sync for March
  • Performance: has been great: tracy/tchung has numbers
  • Not really crashing
  • Q2: Focus on Parity: Tabs, Add-Ons, Forms, ad UI for tablets


Things it would be great to have done for beta:

  • Experience of startup / page load
    • Cut down the amount of checkerboarding - bug 716581
    • Handful of startup weirdness bugs: tracked in bug 721008
  • Fix the p1/p2 font inflation bugs -- we want this to be as right as possible for beta; bug 706193, bug 706198
  • Get frecency / top sites as right as we can: bug 704977
  • Get the in-browser Sync UI pieces in, so people can find and set up sync
  • Get the tab menu not covering the whole screen -- may seem minor, but I want people to get the right idea of how it works as of beta - bug 712526
  • Some thumbnail tweaks around differences in tab menu / start page, scaling where we shouldn't be (bug 721032)
  • UI responsiveness
    • tab menu - opening a tab, switching tabs, deleting tabs
    • aweseomescreen - slow top sites list coming in
    • settings screen - slow for options to becoming enabled

Website Compatibility

(Two-pronged approach)
