Rated 5 out of 5 stars

It's a must have add-on.
For cookies a whitlist is the way to go, but with Web2/Ajax more and more sites rely on JavaScript to work at all, so a whitelist will basically render the WWW hard to use. This is what NoScript would do. Aside that, NoScript is not lighter at alle (look at the size!) and much more difficult to use.
So, because of Web2/Ajax, a blacklist is the way to go for JavaScript. This is what YesScript does and it does it very well. Thanks a lot for it and please keep up the good work!

This review is for a previous version of the add-on (1.3).
