A VPN works across your device, not just your browser, therefore across your mobile apps too. And unlike free VPNs or proxy sites, which may pay for their servers by spying on you and selling your information, { -brand-name-mozilla } does not keep records of where you go and what you do.
VPN 影响着整台设备，囊括了各种各样的应用，而不限于浏览器。一些免费的 VPN 和代理网站会通过监视和出售信息来维持服务器开支，而 { -brand-name-mozilla } 绝不会记录您访问过哪些网站、做了什么事情。
