Firefox starts switching on DNS-over-HTTPS to encrypt lookups, stymie tracking
Mozilla has started to turn on DNS-over-HTTPS, or DoH, as part of its overall strategy of stressing user privacy.
“We know that unencrypted DNS is not only vulnerable to spying but is being exploited,” wrote Selena Deckelmann, Mozilla’s new vice president of desktop Firefox, in a Feb. 25 post to a company blog. “We are helping…to make the shift to more secure alternatives [and] 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.”
