I left too many web pages open and minimized in my dock which caused Firefox to eventually stop responding so I planned to restart the computer and do the restore last session option, which I've done before, so all my open windows would be restored when the computer turned back on. So I started saving some text files I had been working on and starting closing programs that were open and closed Firefox. However the mistake I made was that I accidentally open Firefox again before restarting the computer. It opened and the system restore screen came up but I wasn't ready to restore it yet. I wanted to reset the computer first to clear out RAM memory etc. so it hopefully wouldn't freeze up again. So I closed Firefox again and restarted the computer. When I then opened Firefox again after reset my home page came up, not the system restore screen. Is there any way I can still restore all those open web pages or is it too late?

Is there a temporary folder on my computer somewhere that would contain the website links? Maybe the Firefox crash log files or the recovered files that are automatically generated and stored in trash? --Thanks
