DNS over HTTPS (DoH) is a protocol for encrypting Domain Name System (DNS) queries, enhancing online privacy and security. Traditional DNS queries are sent in plain text, making them vulnerable to eavesdropping and manipulation. DoH encrypts these queries using the HTTPS protocol, which is commonly used for securing web traffic.
Mozilla Firefox supports DoH, providing users with an option to enable it within the browser’s settings. When DoH is enabled, Firefox sends DNS queries to a designated DoH server over an encrypted HTTPS connection. This prevents intermediaries, such as internet service providers (ISPs) or network administrators, from being able to see which websites a user is visiting.
To enable DoH in Firefox, users can navigate to the browser’s settings, find the network settings, and enable the “Enable DNS over HTTPS” option. Firefox allows users to choose from a list of trusted DoH providers or specify a custom DoH server.
By encrypting DNS queries, DoH helps protect user privacy and security, especially on public Wi-Fi networks or in regions with restrictive internet censorship. It makes it more difficult for third parties to track browsing activity or tamper with DNS responses. DoH is an important step towards a more secure and private internet experience.
