The settings you choose to use can be quickly backed up by saving them as a bookmark so they can be restored when you have to reinstall, or transferred to another computer. You can choose to be notified when a script is blocked, so should a site fail to function as expected you can opt to enable individual page elements as required. When you encounter such as site, you can easily add it to a whitelist so that scripts will be allowed to run now and in the future - ideal for banking and shopping sites.
The addon automatically blocks all such content, but there may well be occasions when you need it to run. NoScript is a Firefox addon that can be used to prevent the running of scripts on the sites you visit.
In addition to reducing the performance of sites, there is also the potential for scripts to be used for malicious purposes. You can enable JavaScript/Java execution for sites you trust with a simple left-click on the NoScript status bar icon (look at the picture) or use the contextual menu for easier operation in popup status bar-less windows.Web plugins such as Flash, Java and JavaScript can be used to add a range of interesting features to web sites, but there are also a number of downsides. NoScript also provides the most powerful anti-XSS and anti-Clickjacking protection available in a browser.Ī unique whitelist-based pre-emptive script blocking approach prevents exploiting security vulnerabilities (known and unknown yet!) with no functionality loss. NoScript is an Open Source add-on/extension that provides extra protection for Firefox, Chrome, Flock, Seamonkey, and other Mozilla or Chromium-based browsers.
