1. What are WebRTC leaks?

WebRTC is browser technology that enables audio and video to work in website pages. However, in order to communicate this information, your browser needs your IP address as a point of delivery. A WebRTC leak is when your IP address is revealed during this exchange.

The best VPNs usually come with WebRTC leak blocking to prevent this, but we recommend running your own leak tests periodically to be sure it’s working for you. You can use this leak test tool to check yours now. If your IP address pops up on the results, it means you have a WebRTC leak.

2. Can I get a VPN browser extension for free?

Yes. There are a lot of free VPN browser extensions available, but we don’t really recommend it. Free VPNs often log your personal data, track your web traffic, and sell your information with third parties. The most effective VPNs for Chrome usually come with a price tag, but you get what you pay for in this case.

Check out these best VPNs for Chrome to see what fits your needs.

3. Are VPN browser extensions safe?

Not all VPN browser extensions are safe. Since it’s geared toward only protecting your in-browser connections, they don’t provide the same level of privacy as a full VPN app.

However, some providers like NordVPN require users to run a VPN app and browser extension in tandem. This adds the additional security needed to privatize all internet activity on your device.

4. Are there VPN browser extensions for Safari, Opera, and Firefox as well?

Yes. Many providers offer different versions of their VPN browser extensions. The majority of these extensions can be found in the Chrome Web Store or Firefox Add-Ons Store, but there are also extensions for Opera and Safari.
