IE7 tabs question

Firefox 2 does restore your previous tabs, whether you've said "ok, sure, I know I want to close 7 windows, do it" and close off FF, right? Just wondering if IE does the same, or has some other tab backup facility?

Plus, what are you guys using to save sessions? With FF 1.5, I'm using sessionsaver, but most of the time, you can only select "save this window", not "save all windows"

Use Firefox 3 Beta it allows you to save your session:
