Mozilla this week began piloting its own browser-based VPN service, and if you're located in the U.S. you can start testing it for free right away.
Called the Firefox Private Network, the service promises Firefox users a more secure, encrypted path to the web that prevents eavesdroppers from spying on your browsing activity and hides your location from websites and ad trackers.
In that respect, it won't protect any internet traffic outside of your web browser, but it's a good option if you want to use an encrypted connection on the fly when you're using Firefox on a public Wi-Fi network, for example.
As a time-limited beta, the Firefox Private Network is currently free to try, although this does suggest it may become a paid service in the future. You also need to be a U.S. resident logged into your Firefox account using Firefox desktop browser.
If you can fulfill those pre-requisites, you can install the private network by navigating to this page, clicking the blue + Add to Firefox button, then granting permission for the network to be added to the browser.
Click the door hanger icon that appears at the top-right corner of the toolbar, and you'll see a switch that you can use to toggle the VPN on and off. A green tick in the icon indicates the secure network is active and your browsing activity is being encrypted.
Opera browser offers a similar free VPN service that cloaks your web browsing, but with the added benefit that it lets you choose the continent that you want your connection to reside. So if you're looking to access a location-restricted service (Netflix, say) from abroad, you might have better luck using it instead.
