You can use about:config to control this, although it's significantly 
less convenient. You could switch to using seamonkey, which is similar, 
but lets you control more stuff through preferences. I have heard mentions 
of other extensions for turning javascript on and off easily.

Note also that they have also removed the ability to disable loading of 
images. As far as I know you can't even do this with about:config.
