I am on the beta channel of Firefox (currently 17.0, by the about window) and I cannot seem to find a way to limit the size of a browsing session that is automatically restored when re-opening the browser. In the past, Firefox would only save sessions of more than one tab when closing the entire application, and ask me about restoring said session when restarted. Now, Firefox seems to treat a session of just a single tab the same, which is a preference I dislike, given that I use a blank start page to great effect.
I am using a number of addons, including Tab Mix Plus, which specifically modifies tab behavior (although I have it configured to use Firefox's default session manager), but the problem persists even with all addons disabled.
I cannot seem to find an option in about:config to change this behavior. Is this a permanent change within Firefox, and if so, is there or will there be an option to specify the number of tabs that constitute a session that will be automatically saved?
