The browser also offers additional security features, such as HTTPS Everywhere and NoScript, which can be enabled to provide additional protection against malicious websites and tracking scripts. Additionally, the Tor Browser is compatible with a variety of popular plugins, such as Adblock Plus, which can be used to block unwanted advertisements and other tracking scripts.
