== Summary ==
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.

== Release Requirements ==
* Ability to toggle on-demand loading of tabs.
== Designs ==
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
== Next Steps & Open Issues ==
* Talk to Paul about estimates & tracking
== Related Bugs & Dependencies ==
* {{bug|648683}}
== Risks ==
* 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.
