Question : Firefox session restore - start without it

I got into a situation where over 100 tabs were opened (bookmark root).
Now I need to get into Fx without it attempting to restore those tabs - it hanged which is why I had to kill it in the first place.
Which file do I edit or command line switch can I use?

Answer : Firefox session restore - start without it

This page shows how to kill that feature which I had to do: http://kb.mozillazine.org/Session_Restore  In "C:\Program Files\Mozilla Firefox\defaults\shortcuts" is a shortcut for "Safe Mode".  More info here: http://kb.mozillazine.org/Safe_mode
