Should I use a VPN app or a browser extension?

This depends on your needs. VPN browser extension encrypts and anonymizes only your browser’s traffic, while VPN app covers all your internet traffic. So if you want to mask only your browser’s traffic and leave other connections unaffected, use VPN browser extension. In other cases, it’s better to use the fully-featured VPN app. You can learn more about differences between VPN app and VPN extension in this article.
