NoScript also allows you to select which scripts you want to allow. It's not all or none. You can also view the source before you decide to let it run.

I very clearly remember, many years ago, a site (which was otherwise perfectly usable) nagging me to "enable JS for a better experience"; curious, I did and was immediately assaulted with all manner of hostile and irritating crap like popups, text selection hijacking, and even attempts to disable the right-click menu. Hurriedly disabled JS again to regain sanity. Nope. I'm never falling for that again... Of course the problem these days is with sites that don't work at all without JS even if they're just static content, and I suspect part of the reason is to force-feed you the crap along with the real content.
