When the first version of the Restore Session tab was implemented in an update for Firefox?

more options

Essentially, I'm trying to find out how many sessions I can restore since, after the creation of this feature, I typically allowed the "Restore Session" Tab to remain in the window, allowing me to at least access the last few sessions later on when I'm much less busy. Unfortunately, I let it get a bit out of hand. Is there any way for me to find out how many sessions I have saved in this way by searching through files or folders affiliated with this browser? Even if the history clears about every 290 something days, are these sessions and the information they require stored in such a way that the clearing of history would not create a problem if I want to restore very old sessions that were left in this manner? (I recently changed it to allow all of my history to be saved, rather than just limiting the number of days, but I fear I might have taken this action too late. And I'm going to download a "Session Manager" add-on, to help me with this in the future, but, I'm still worried about these past sessions.) Any help or information would be appreciated. Thank you for your time.

You can only manage multiple sessions with an extension like Session Manager (extends the build-in session restore) or Tab Mix Plus (has its own implementation of session restore, so can be less reliable if Firefox doesn't close properly). The basic build-in Firefox session restore only handles the previous session. Firefox 4 has a button on the about:home page and a menu entry (History > Restore Previous Session), but Firefox 3 doesn't have that feature. Session Restore stores a list of currently open tabs, so the amount of history that you keep shouldn't matter.

I remember that older versions only stored the one previous session, but these session restore pages "Well, this is embarrassing..." seem to be capable of holding the old restore session pages if you don't close them, so I'm able to access at least the past two or so, as I clean out the more recent session. Do these pages not require the history to open up the pages and the sequence of pages for each tabs? Where is the information for restoring sessions typically kept on the computer? I'm a little bit confused about these things, but thank you for your reply.
