Encrypted Client Hello Support
Firefox 119supports Encrypted Client Hello officially now. You can check out the full article on the introduction.
Encrypted Client Helloimproves the privacy of connections by encrypting information about the domain name during connection attempts. Previously, anyone listening in on network traffic, including ISPs, could monitor the information.
Some ISPs sell information about user activity on the Internet, others may use DNS-based blocking to prevent access to certain sites. With Encrypted Client Hello , DNS -based blocking is no longer effective.
Note that servers need to support this well to work.
Mozilla implemented several privacy enhancements in Firefox 119. The two core additions are the partitioning of Blob URLs and limited visibility of fonts that websites have access to.
The firstmitigates a potential tracking vector that third -parties may utilize for tracking purposes. This was the only state partitioning test at Privacy Tests that Firefox failed at.
The limitation of fonts improves Firefox‘s defenses against font fingerprinting by restricting sites to system fonts and language pack fonts.
