Firefox immediate lockup trying to restore memory-leaking open tabs

I've managed to get firefox to immediately lock up once opening it as it's trying to restore a tab that causes the memory so suddenly leak so severely the memory graph in windows is greater than 45 degrees. Firefox does have option to turn of tab-reopening on launch, but that requires being able to use the options menu, or even about config screen. Restarting the computer, end-task on firefox and re-launch, or spam clicking the close window box, or ctrl-w to try to close tabs, all have failed.

Is there a way to launch firefox perhaps with a command line or key hold that prevents it from re-opening a previous session?

Look for the Firefox icon on your Task Bar. Right click and select Open New Window.

I'm on Windows XP, so you can't do that on the task bar (it just shows the standard window actions menu). You also can't re-launch firefox from the start menu, because the process is already locked up.

I've read that you can start firefox in safe mode (hold down option key while opening) and it won't restore your session, but testing this it doesn't appear to work.
