I closed several ( 5-6) firefox windows when shutting down my computeer, and after re-staring firefox chose to 'restore previous session' (set by default but failed to so automatically this time). Saddly, in my about:config there was the default of opening only 3 windows, which means that all the others windows and tabs are now gone. My question is: can I fin out in the history, or or in the some firefox log files, the address of the pages that were open in those windows/tabs. A list of all closed tabs and the time they were closed would suffice. The 'recentely closed tabs' options does not appear to contain that information, only the tabs that were closed in the current window. Details: OS: Linux Ubuntu 14.04 Firefox 35.0.1 Cheers.
