Comment 72 for bug 483929

an additional tweak based on feedback by zpao: we should have the first tab be the user's home page (or set of home page tabs), and the second active tab be about:session restore. This way the message does have a close button on the tab (since there is more than one tab) and there is even one more target for the user to indicate that they aren't interested in restoring right now.

We will end up doing this implicitly when we load the home tab and other application tabs, so we could just land this knowing that those other targets are going to be available later. (or we could add the home page now, really either way).
