Firefox starts using dns encrypted over https
Table of contents:
Mozilla has announced that its Firefox browser has started to deploy encrypted DNS over HTTPS by default for all users in the United States. This is an important step in the drive to fully encrypt all Internet traffic and eliminate the risk of attack.
Firefox begins to use encrypted DNS over HTTPS in American territory
However, while Mozilla is pushing the role as "one of the many privacy protections that can be expected from us in 2020, " it could be preparing for a long legislative battle. Why?
On a technical level, DNS over HTTPS (DoH) encrypts the initial search of the website you want to reach, known as the 'Domain Name System'. "DNS is a database that links a human-friendly name, such as www.mozilla.org, with a series of computer-friendly numbers, called IP addresses (for example, 192.0.2.1), " explains Mozilla. "By performing a 'search' on this database, your web browser is able to find websites on your behalf."
Since these split-second requests also include your IP address, a hacker could take that information to create an online profile of you and the sites you visit, or the server itself may be collecting your data for advertising or marketing purposes, often without your knowledge.
By enabling the default DNS over HTTPS, Firefox assures users that it is only using trusted servers - Cloudflare and NextDN at first - that they are "committed to throwing out all personally identifiable data after 24 hours, and never to pass those data to third parties ”. So if you use the Firefox browser in the US, your internet traffic will bypass your ISP's server and redirect it to Cloudfare or NextDN to ensure encryption from start to finish. It's kind of like browsing through a VPN without actually accessing one.
The reason the default DoH is limited to the US It is due to the UK's own efforts to block child porn and other sites at the request of the government. The default DoH would make it much more difficult for ISPs to implement filters to prevent the disclosure of child porn and other sites prohibited by law.
The DoH feature enabled in Firefox is also offered in Chrome, Opera, and Edge (Chromium) browsers, but it is not enabled by default and it is not that easy to implement.

Finally, the US government Also be wary of DNS over Google's Chrome browser, which offers the DoH option, but not by default, came under fire last year from the House Judiciary Committee "because of concerns that it might give the company an edge. competitive by making it difficult for others to access consumer data, ”according to The Wall Street Journal. In addition, ISP cable and telecom providers are also concerned that the DoH will break "critical Internet features and functionality, " including parental controls, and that it "undermine the efforts of the federal government and the private sector to use DNS information. to mitigate the risks of cybersecurity ”.
We will see how this topic evolves and if Firefox managed to implement the technology without government restrictions. We will keep you informed.
