It seems to work fine with Firefox 3.6.10 Windows XP.
But it's useless for me, like all the other restart addons, because I want to have all my cookies deleted after closing Firefox, but this doesn't seem to work with these restart addons.

Thank you for your comment! I'll take it as a complaint/request and try to include some cookie cleaning functionality.
