After a brief delay, Mozilla has started to make DNS over HTTPS the default for Firefox users in the US. Notwithstanding any additional hiccups, the company says it hopes to finish the rollout sometime over the next couple of weeks. The protocol is supposed to protect one of the most fundamental aspects of browsing the internet: translating URLs into IP addresses. Without DNS over HTTPS, bad actors can see what websites you've visited -- even if they don't know what you did on those sites thanks to HTTPS. The protocol protects your privacy by effectively disguising DNS queries as regular HTTPS traffic.
