NoScript is an open source and advanced web browser extension that provides extra protection against a wide array of vulnerabilities for Firefox and SeaMonkey users, as well as make the browser a lot more faster by blocking unnecessary content for a better and improved browsing experience.
Makes it simple to block all scripts on a website
In other words, NoScript will allow active content to run only from sites you trust, and protect yourself against XSS and Clickjacking attacks.
Whitelist for unblocking scripts manually
Furthermore, if you do not want to unblock them for good, you can also choose to enable them to run only temporarily just in case you don’t really trust the website you’re browsing that much and it will suddenly decide to change its security and privacy behavior in the future.
Protects against known or unknown web browser vulnerabilities
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.
In you want to add a website to its whitelist, NoScript makes it easy to use to do so by adding its domain. This will implicitly also mean that all of the sub-domains will also be whitelisted, therefore you will have to be careful and analyze the website’s structure beforehand to prevent accidentally running a script or other automated scripts unknowingly.
Blacklist for blocking everything on untrusted websites
If you want to be a little more drastic with websites that you know to often launch pop-up windows or to run disrupting ads, you can use NoScript to add them to an untrusted blacklist which will effectively block all annoyances and greatly improve your web browsing experience.
Multi-platform solution for enhancing your browser’s security and speed
As an added bonus, the NoScript add-on is also cross-platform and it has been tested on Mac OS X, Windows and Linux. Thus, NoScript will virtually allow you to effortlessly enhance both your internet browsing speeds and your privacy on all the most popular operating platforms.
