I closed my browser and a "new version" of Firefox was installed. MY ENTIRE HISTORY WAS ERASED!!! I CANNOT "RESTORE PREVIOUS SESSION".... I AM N O T HAPPY! WHY WOULD YOU DO A THING LIKE THIS? GET MY PREVIOUS SESSION BACK AND ALL MY HISTORY! THERE ARE OTHER BROWSERS.... I HAVE USED FIREFOX FOR YEARS AND THIS IS THE FIRST TIME THAT I HAVE BEEN ABSOLUTELY ENRAGED! WHY DON'T YOU ASK US IF WE EVEN WANT AND "UPGRADE"! PLEASE RESPOND!
