I think a fair question to ask is, "If you do not understand the internet, should it be easy to disable javascript in your browser?"
As a person who uses noscript every day in FF, at first I thought this was a bad idea, but the more I think about the support aspect of this, the only time I think you really should turn off JS is when you understand enough to find the advanced options.
I hate javascript with a fiery passion. But I'm sensitive to (possibly real) arguments that people are accidentally disabling it because they start clicking random stuff in the 'content' tab of preferences. So move it to 'advanced' and call it a day.
