These Weeks in Firefox: Issue 25


Friends of the Firefox team

Project Updates


Activity Stream

  • Update on Activity Stream on about:home for 57
    • Landed patch to restore existing about:home in Nightly, preffed off by default
    • Starting a Shield pref flip study in Nightly to compare Activity Stream to existing about:home
    • Requested uplift for patch to 57 Beta so that same study can be run there
  • Started planning / landing for 58

Browser Architecture

  • XBL design review happened last week, next step is to share the plans more widely.
  • Experimenting with removing the XUL box model

Firefox Core Engineering

  • New projects († are subject to approval):
    • Adding a dummy crash reporter (en route to CFI-based stackwalking)
    • Jumping in to help with Chrome migration
    • Going to be creating a policy engine & API to support policy management in enterprises (not just Active Directory)†
    • Possibly revamping how we update the DLL blocklist† in parallel with some early injection mitigation changes

Form Autofill

  • Working with the SHIELD team to do the gradual rollout of address autofill in 56
    • One bug fix needs deployment first
  • Continuing work on credit card autofill for the US (not riding the trains yet)
  • “Clear” autofill item in progress



  • Been doing a deep-dive investigation on this bug where a user reports slower page load times due to the 60fps tab throbber
    • We’ve now got hardware where we can reproduce the problem on. The clock speed is really low on these machines (even worse when in battery-saving mode), which seems to be the main contributing factor.
  • Fixed a bug where logins / passwords weren’t being filled in via the context menu item – this was a regression from some perf work where the contextmenu sync IPC message was removed.
  • Patches will land shortly that will allow us to kill hanging JS more quickly in content processes when we’re shutting down or when all windows have disappeared. This should eliminate a class of slow shutdowns.
