Will A System Restore Bring Back Previous Firefox Session?

more options

Firefox failed to bring up my previous session of 30+ tabs from 3 days ago and my most recent sessionstore.js file is of today's date. Will a system restore back to 3-4 days ago return the sessionstore.js file from that day? If not, is there any other way I can bring back that session?

(NOTE: Suggesting ways to prevent it from happening in the future is not what I'm looking for, only a solution to my current problem.)

I doubt if that will restore your session. Chances are that doing a System Restore will break Firefox altogether from what I have seen posted here over the years.
