I have version 3.6.17. I just updated it. Today, something happened that caused me to lose my most recent session (which I had been reopening each time using Firefox). I've been trying to either restore that session of trying to find all the tabs I had. I have been looking at my browser history to find the tabs, but I've noticed that some of my history is missing. How is this possible? Is there any way to find the missing parts? I am also using Windows XP. Also, this happened June 23, 2011. Please help! I want to find my tabs again. Please help me! Thanks.
