|Feature open issues and 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.
|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.)
|Feature requirements=* Ability to toggle on-demand loading of tabs.
|Feature ux 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.
