This video delves into the current landscape of browsers featuring built-in VPN functionality, with a particular focus on evaluating the actual privacy protection capabilities of mainstream options like Brave, Opera, and Tor. The video points out that most popular browsers suffer from significant data collection and tracking issues, and that the quality of browsers claiming to have built-in VPNs varies greatly. The Brave browser stands out with features like ad blocking, script blocking, and a password manager, but its VPN functionality is currently limited to the iOS version. Opera's so-called VPN is actually a flawed proxy service with numerous third-party permission vulnerabilities. Niche browsers such as Aloha, Epic, and UR have been exposed for false advertising and mandatory data collection. While the Tor browser offers extremely high security, its network speed is prohibitively slow and it can be easily detected by ISPs. The video ultimately recommends Brave or Tor, combined with a professional VPN service (like NordVPN), for genuine privacy protection, suitable for professional users who require multi-account operations for cross-border e-commerce and data security protection.
