Which Firefox VPN Extension You Must Avoid?

Opting for free VPN service in itself is a risky proposition because many services impose limitations that hinder your entire experience. Injecting advertisements, imposing bandwidth throttling, data caps, and waiting queues are common for “free” products.

In the marketplace, there have been many instances of free VPNs taking advantage of layman users by stealing their data, deploying botnet attacks, and selling information to third party services. Among some of the worst free options you should avoid at all costs, include:

  • Turbo VPN: Apart from having obvious links to China, Turbo VPN has no official presence online, except for availability in app stores and social media, where they are unresponsive. There is no website, terms of service, privacy policy, or any info about the service.
  • Hola VPN: This highly ridiculous and treacherous service was involved in botnet attacks wherein they utilized idle bandwidth of their own users, instead of from their own servers. There was even an instance of a data breach, affecting a lot of users worldwide.
  • Setup VPN: A suspicious VPN from the first sight, this free option is not at all trustworthy and keeps extensive activity/connection logs, which includes information like referring web site addresses, access times, IP address, pages visited, etc.
  • Hotspot Shield: The VPN is a famous choice for many but it offers no incentives for securing and anonymizing your data. The provider also gets blocked by most streaming services around the world, and simply just fail at keeping your identity secure!
