NoScript is a content filtering application that modifies web browser behavior on the fly. You can use it to block JavaScript and Flash on websites, and set the NoScript whitelist to allow it only for trusted domains. NoScript protects you from malicious sites that want to trick you into installing malware and steal your data. It also prevents various other security issues.

To enable NoScript, visit your browser's Settings, and then click the "Accept" button. It's that simple!

NoScript's whitelist has an optional expiration, but it does not prevent you from opening a website in a new tab and accessing the website from there. It will stop the website from doing anything to your device, but it will not stop malicious sites from loading in your browser.
