Block Scripts in Firefox, Protect yourself from Clickjacking

Here’s an easy way to protect yourself on the Internet from cross-site scripting attacks and clickjacking. Just install this free add-on called “NoScript” that will provide extra protection for Firefox, Flock, Seamonkey and other mozilla-based browsers.

NoScript blocks all scripts from running until you authorize them.

For trusted sites, you could:

Enable JavaScript, Java and plugin execution with a simple left-click on the NoScript status bar icon
Or, use the contextual menu, for easier operation in popup statusbar-less windows
