NoScript is a complex extension that provides extra protection for Firefox and SeaMonkey.
In other words, NoScript will allow active content to run only from sites you trust, and protect yourself against XSS and Clickjacking attacks.
NoScript is a free, open source and enables JavaScript, Java, Flash and other plugins to be executed only by trusted web sites of your choice (e.g. your online bank), and provides the most powerful Anti-XSS protection available in a browser.
NoScript's unique whitelist based pre-emptive script blocking approach prevents exploitation of security vulnerabilities (known and even not known yet) with no loss of functionality.
The NoScript add-on is cross-platform and it works on Mac OS X, Windows and Linux.
Here are some key features of "NoScript":
· Usable security.
· Site matching.
· Beyond JavaScript: also blocks Java, Silverlight, Flash and other embedded content.
· Untrusted blacklist.
· Anti-XSS protection.
Requirements:
· Firefox 3.0 and later or
· SeaMonkey 2.0 and later
