Rated 5 out of 5 stars

Simple, effective, lightweight and perfect. This is an essential extension for all Firefox users. Please keep it updated!

I tried QuickJava and NoScript, only to finally stumble across this one which was exactly what I needed.

NoScript is overwhelmingly heavy for today's secure and fast browsers. It weighs in at 427KB and has a thousand options. YesScript is ideal for blocking a handful of sites. It's only 43KB and does one thing effectively: blacklist sites from JavaScript.

This review is for a previous version of the add-on (1.6).
