You probably have a dozen extensions installed. Do you know what each one can actually see and do?
Some extensions can read every website you visit — including what you type, your passwords, and your login cookies. Most people have no idea, and in 2026 several popular extensions were caught quietly collecting user data. "Is This Safe?" gives you a clear answer in one click.
