NoScript Firefox extension

NoScript Firefox extension provides extra protection for Firefox, Flock, Seamonkey and other mozilla-based browsers: this free, open source add-on allows Javascript, Java and 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.
