I've tried almost everything so far: Checking my settings/preferences in '''tools''' to make them what they need to be for restoring my tabs. Deleted ''sessionstore.bak'' and ''sessionstore'' files in my profile '''open containing files''' (wasn't a ''sessionstore.js'' file to delete though). Also tried running in '''safe mode''' to check add-ons, extensions, etc. to see if they were causing the problem. The ''about:config'' settings that apply to this problem are all on "true". So far when I close firefox, by clicking the x-button on the top right corner, my tabs ''are'' still there when I re-open firefox. But I want it to ASK me to "save tabs" and TELL me when "your about to close multiple tabs". What am I doing wrong? Anyone?
