Firefox 18.0.1 running on Windows 7

When Firefox crashes, the next time it opens it tries to restore the previous session. I do not want Firefox to restore the previous session after a crash. How do I prevent Firefox from restoring the previous session after a crash?

Please note: 1- My home page is set to "blank page" 2- I have configured Firefox to NOT remember my browsing history, download history, form fields and passwords. 3- Even in Safe Mode (i.e., with all add-ons disabled), Firefox STILL restores the previous session after a crash.

hello Bulldogger, please try the following in order to switch off sessionrestore completely: enter about:config into the firefox location bar (confirm the info message in case it shows up) & search for the preferences named browser.sessionstore.max_tabs_undo and browser.sessionstore.max_windows_undo. double-click on those entries and change both of their values to 0.
