Why Download KeepSolid VPN Unlimited for Firefox

When you set up VPN Unlimited browser extension you will receive all the benefits of our security plugin. Concerning the world of online privacy, it gives you even more protection in case you use web browsers with the WebRTC protocol applied by default.

What is WebRTC leak

The WebRTC technology allows revealing a user’s local and public IP address to all concerned parties, even if a VPN service is enabled. This can affect your personal data: including credit card details, passwords, or even your location.
