The 'must have' Add-On.
P.S. to all who critizise the GUI: to use the new GUI is a bit different, but once understood it is as intuitive and fast to use as before. Really a great tool!

It's very simple : First when I was visiting some web sites, the CPU seemed to be suddenly panicking ! Now, I just active restrictions globaly for this site. Result: I get all the informations I needed without all this garbage of unwanted pubs !!! Thank's for that :-))

It's so good to security and even to ads! Thanks for this amazing tool!

This add-on just saved my account. I got a phishing e-mail that looked like it was legitimate, but the link pointed to a domain one letter off the original. The site didn't load properly because scripts were blocked on it. I knew I had scripts allowed for that domain. This helped me realize that the domain is not legitimate.

I initially installed this in my Firefox when there were many Javascript vulnerabilities, but these days it shows me that Facebook is trying to run a script with my on-line banking session at my credit union and at my trade union web site. NoScript allows me to mark that as "Untrusted," but these services still work fine without it; perhaps even better. NoScript lets me put that Facebook creep back in its place. Love it!
