Mozilla has rolled out a test version of its VPN extension called Private Network for Firefox browser users. So far, the system is only available in the U.S. and only for desktop versions of the program.

The use of the protocol in practice means the ability to bypass any blocking of banned sites on DNS using the Firefox browser. All DNS requests will be transmitted in an encrypted form, and locks on the IP address will be overcome by changing the blocked address IP.

At the moment, services are free, but in the future more likely we“ll have to pay for it. This system has already been presented for free in the Opera browser for quite a long time.
