Firefox not warning when closing multiple tabs

I had this problem when I upgraded to Firefox 3.6 and there were all these discussions on changing the settings - none of which worked. After fiddling around I accidentally discovered that if I set my Privacy settings to "Never Remember History" it would always close multiple tabs without warning regardless of what other settings for tabs are set. I got around to changing my Privacy settings to clear history on close.

Finally, one aggravation solved.
