always restoring the previous session (without asking) is much harder to find. Now a bit of Googling turns up innumerable posts about disabling session restore so you always start a new session, but finding information about the opposite behaviour, i.e. Clicking ‘Resume Previous Session’ all the time really hacks me off. I always want to restore as the first 5 or 6 tabs are my ‘always open’ apps (GMail, Google Reader, etc,). Next time I restart the browser it asks me if I want to resume the previous session. I often shutdown my machine without closing Firefox.
