User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1) Gecko/20090624 Firefox/3.5 (.NET CLR 3.5.30729)

When "Clear history when Firefox closes" is turned on, session restore is unable to function.  The problem with this is that with this setting turned on, the browser does not warn that multiple tabs are being closed when the last window is closed even though the tabs will not be restored.
Each of these behaviors make sense independently, but when combined, they are not good.

Reproducible: Always

Steps to Reproduce:
1. Turn on "Clear history when Firefox closes"
2. Turn on "Warn me when closing multiple tabs"
3. Turn on "Show my windows and tabs from last time"
4. Open multiple tabs in 1 window
5. Close the browser
Actual Results:  
The browser's tab state was lost with no warning given.

Expected Results:  
The browser should issue a warning that multiple tabs are being closed when the browser is closed.
