Unable to restore last session after installing latest security update (20150630154324) for Firefox 39.0. This happened when version/security update as well and is unbelievably frustrating. Under 'Bookmarks' menu, the 'Restore previous session' option is greyed out. I have selected "Show my windows and tabs from last time" from the 'Options General' menu but it still does nothing.

I have sorted this out but I cannot use Mozilla if this continues. I lost hours and hours of research work. Basically gone.
