Script blocking tools play a significant role in safeguarding users’ privacy and protecting against various online risks. This article explores the top script blocking tools available and highlights their key features, benefits, and best practices for using them effectively.

With the rise of sophisticated online threats, including malicious scripts embedded in websites, users need robust defenses to ensure their online safety.
