Open issues/risks

`

Stage 1: Definition

1. Feature overview

Session restore makes restarting the browser a frictionless experience.

2. Users & use cases

Starting up the browser is a common experience for all Firefox users. Many Firefox users have session restore turned on and we intend to make that the default in an upcoming release. Session restore can cause the browser to start up more slowly than without session restore. Changes that make session restore have less of an impact on startup time will allow us to enable session restore without users being bothered by slower startup times.

3. Dependencies

`

4. Requirements

  • Restoring a session at startup must be on par or only negligibly slower than not restoring a session.
  • Restoring of the session is the default behavior.
  • Tabs are loaded on-demand by default.
  • Users are notified the first time a session is restored by default, and given the opportunity to disable the feature.

Non-goals

  • Restore a session in a more comprehensive manner than we do currently.

Stage 2: Design

5. Functional specification

`

6. User experience design

The user is notified of the first default session restore by an infobar that says something like:

"Firefox has restored your previous browsing session. If you want, you can change this behavior."

And has a button labeled "Configure", which opens the preference window to the General tab.

Stage 3: Planning
