If you check the don't show this again box when closing multiple tabs, how do you get it to warn you when closing multiple tabs, or to save previous tabs? Checking the warn me when closing multiple tabs box under tools/tabs does not work to solve this?
I accidentally checked the do not ask me again box when closing multiple tabs. Now I no longer get a warning when closing multiple tabs, and it saves my previous session. I have tried checking and un-checking the warn me box under tools which has not worked. If I open a second window and try to close multiple tabs it will warn me but not on the first window.

Start in safe mode and reset preferences: https://support.mozilla.com/en-US/kb/Resetting+preferences?s=safe+mode&as=s
You can reset the warn prefs on the about:config page via the right-click context menu.
browser.tabs.warnOnClose , see http://kb.mozillazine.org/About%3Aconfig_entries browser.warnOnQuit , see http://kb.mozillazine.org/browser.warnOnQuit browser.warnOnRestart , see http://kb.mozillazine.org/browser.warnOnRestart
To open the about:config page, type about:config in the location (address) bar and press the "Enter" key, just like you type the url of a website to open a website.
If you see a warning then you can confirm that you want to access that page.
