Is MetaMask safe from hackers?

Could you please elaborate on the safety measures that MetaMask has in place to protect users from potential hacking threats? Are there any specific features or protocols that MetaMask employs to ensure the security of user funds and sensitive information? Additionally, what steps can users take to further enhance their security when using MetaMask? I'm particularly interested in understanding how MetaMask addresses the ever-evolving landscape of cyber threats and how it stays ahead of potential vulnerabilities.
