Stage 1: Definition
1. Feature overview
Most users prefer starting the browser right where they left off. Firefox is moving to a model that restores all tabs when a user starts up the browser but delays the loading of background tabs until they are needed. This will improve the performance and usability of Firefox just after launch.
Context:
- The ability to delay-load background tabs was originally developed as part of bug 586068, "Cascade page loads when restoring".
- There is no feature page but there is a security review for the feature.
- An about:config and UI boolean preference for this was implemented in bug 648683, "Expose tabs on-demand preference" (feature page).
- This feature page is about enabling the boolean preference by default. See bug 711193 for more detail.
- The final goal is to make it the default to restore the previous session on startup, without affecting startup performance, or responsiveness just after startup.
