Open issues/risks

  • Talk to Paul about estimates & tracking
  • There are cases where you want all tabs to load in the background. We'd like to expose the preference to enable the old behavior for the people that prefer this.

Stage 1: Definition

1. Feature overview

Firefox 4 has the hidden ability to load tabs on-demand by setting the maximum number of concurrent tabs being restored to "0" — now that the feature has been in the wild for a while, we'd like to expose it as the default behavior for session restore. It makes startup a lot faster, and uses a lot less memory.

This feature falls primarily in the Experience category (from the "Discover, Experience, and Connect" vision statement.)

Stage 2: Design

5. Functional specification

`

6. User experience design

When you select "Show my windows and tabs from last time" in Prefs -> General, we should show an indented checkbox "Load on demand" that toggles this setting. This should be enabled by default.
