Today, Firefox began the rollout of encrypted DNS over HTTPS<\/a> (DoH) by default for US-based users. The rollout will continue over the next few weeks to confirm no major issues are discovered as this new protocol is enabled for Firefox\u2019s US-based users.<\/p>\n

A little over two years ago, we began work to help update and secure one of the oldest parts of the internet, the Domain Name System (DNS)<\/a>. To put this change into context, we need to briefly describe how the system worked before DoH. DNS is a database that links a human-friendly<\/i> name, such as www.mozilla.org<\/a>, to a computer-friendly<\/i> series of numbers, called an IP address (e.g. 192.0.2.1). By performing a \u201clookup\u201d in this database, your web browser is able to find websites on your behalf. Because of how DNS was originally designed decades ago, browsers doing DNS lookups for websites — even encrypted https:\/\/ sites — had to perform these lookups without encryption. We described the impact of insecure DNS<\/a> on our privacy:<\/p>\n

Because there is no encryption, other devices along the way might collect (or even block or change) this data too. DNS lookups are sent to servers that can spy on your website browsing history<\/a> without either informing you or publishing a policy about what they do with that information.<\/em><\/p>\n

At the creation of the internet, these kinds of threats to people\u2019s privacy and security were known, but not being exploited yet. Today, we know that unencrypted DNS is not only vulnerable to spying but is being exploited, and so we are helping the internet to make the shift to more secure alternatives. We do this by performing DNS lookups in an encrypted HTTPS connection. This helps hide your browsing history from attackers on the network, helps prevent data collection by third parties on the network that ties your computer to websites you visit.<\/p>\n

Since our work on DoH began, many browsers have joined in announcing their plans to support DoH<\/a>, and we\u2019ve even seen major websites like Facebook move to support a more secure DNS<\/a>.<\/p>\n

If you\u2019re interested in exactly how DoH protects your browsing history, here\u2019s an in-depth explainer by Lin Clark<\/a>.<\/p>\n

We\u2019re enabling DoH by default only in the US. If you\u2019re outside of the US and would like to enable DoH, you\u2019re welcome to do so by going to Settings, then General, then scroll down to Networking Settings and click the Settings button on the right. Here you can enable DNS over HTTPS by clicking, and a checkbox will appear. By default, this change will send your encrypted DNS requests to Cloudflare.<\/p>\n

Users have the option to choose between two providers — Cloudflare and NextDNS — both of which are trusted resolvers<\/a>. Go to Settings, then General, then scroll down to Network Settings and click the Settings button on the right. From there, go to Enable DNS over HTTPS, then use the pull down menu to select the provider as your resolver.<\/p>\n

\"\"

Users can choose between two providers<\/p><\/div>\n

We continue to explore enabling DoH in other regions, and are working to add more providers as trusted resolvers to our program. DoH is just one of the many privacy protections you can expect to see from us in 2020.<\/p>\n
