This is one of my favorite addons and a large reason I use firefox over Opera the majority of the time, the script allows you to disable the Javascript on websites well yeah you can go to options and untick the enable javascript box but this is so much more.
Here is a screen shot of it on Jace’s website:
From this screen shot you can see a lot of things for example you can see all the different scripts from different sites like google analytics or mybloglog so you can allow these different scripts.
What is the need for it though, well if you know your stuff about internet security you will notice how dangerous javascript can be to your browsers it is a very dangerous hole in your computers defence, so only allowing sites you trust is a brilliant method or if your not sure you can temporarily allow the websites.
You can download it from the mozilla website here or from their own site here noscript.net.
