| Open Firefox, go to Tools-Options- General-Startup- When Firefox Starts-
Select- "Show my windows and tabs from last time".
After selecting this option even if you close multiple tabs at once firefox will open your all windows and tabs that you closed last time.
And if you need WARNING while closing multiple tabs just go to Options-Tabs- and "Check" the option "Warn me when closing multiple tabs
Hope this helps.
