Firefox 39.0 on Win 7 just suddenly crashed and cannot recover my lost previously open windows/tabs. If something like this happened to me before there was an option Re-open previous Windows/Tabs in the new Tab. Not now - just new window without that option. Previous Session and Closed Windows are Gray in History tab. I can see single links in the History for July, June, May but cannot get back previous Tabs/Windows from last night/this morning before the crash happened. Tried also Right-click the current file > Properties > Previous Versions = There is nothing. Is there some other solution how to recover all those previous tabs/windows please? I had a lot good links opened there, sad now. Thanks a lot!
