I supppose too many people accidentally disabled Javascript in recent months while trying to disable Java. As long as there's an about:config option that does the same thing, I don't think it's a bad move to remove that option from view.

I will, however, miss the "Advanced" button next to the "Enable JavaScript" checkbox (if that button is going to go away, too, which the article isn't clear about). I use those Advanced options all the time to prevent websites from messing with my neatly tiled windows and trying to prevent me from using the right mouse button. Here in South Korea, the majority of blogs and forums have right-click protection enabled (and refuse to display any content if you disable Javascript altogether) due to ridiculous defaults in popular platforms, and every other website feels like they have the right to go full-screen. Firefox is the only thing that makes this stupid trend bearable. I guess I'll have to go and check whether NoScript has a similar option.
