Firefox users have acquired another web barrier that increases privacy on the Network.
Our online activities and communication are constantly monitored. Despite the association of online surveillance with advertising networks, our activity is constantly caught in commercial telecommunications networks, which, among other things, use our browsing history for their own benefit.
(ECH) changes the situation
Encrypted Client Hello (ECH) is a mechanism developed by Mozilla that encrypts the very first "hello message" between the user's device and the site server, which allows you to keep the name of the site you are visiting secret. Recently, ECH was implemented for all users of the Firefox browser.
Mozilla has been working on this technology for five years in collaboration with other browser developers, researchers, and organizations such as the Internet Engineering Task Force (IETF). Although many of our data, such as passwords and credit card numbers, are already securely protected using cryptographic protocols, ECH additionally protects the identity of the sites we visit.
How does it work?
Usually, when a browser connects to a site, it passes the name of that site in its unencrypted initial message. ECH, in turn, uses the public key obtained through the DNS system to encrypt this first message, increasing user privacy.
With Firefox's ECH technology, users can be assured of greater privacy for their online activities. However, browser support for ECH is only half the battle. Web servers must also implement ECH support on their part. So, Cloudflare already provides ECH support, and it is expected that other providers will also start doing this in the near future.
ECH works in conjunction with other security and privacy features in Firefox, including DNS-over-HTTPS (DoH) technology. DoH and ECH can also be combined with virtual private networks (VPNs) for added protection.
Continued pursuit of privacy
Many years ago, Mozilla started working to modernize and protect DNS, eliminating data leaks. At the same time, work began on the protocol that became the predecessor of ECH. Mozilla's contributions to standards such as DoH, TLS1. 3, and QUIC have played a crucial role in shaping the modern online privacy landscape.
Mozilla has long invested in technologies that protect the privacy of Firefox users. ECH provides users with an even higher level of protection. This technology is an indicator of the company's continued commitment to the ideals of privacy and security.
