Protect your DNS requests with DoH

The Domain Name System (DNS) enables you to access websites with a name rather than an IP address. Mozilla has taken action to protect your DNS requests from tampering and tracking by championing the DNS over HTTPS (DoH) standard and implementing functionality that supports it in Firefox.

In the United States, DoH functionality is enabled by default, although you can choose to deactivate it.

Outside of the US, you can manually activate DoH.

Log into multiple accounts at once—and avoid Facebook tracking cookies

With Multi-Account Containers you can simultaneously log into the same site with different accounts in different tabs.

You can even sync your container settings across devices if you have a Firefox Account to save the data in.

Facebook Container is specifically designed to make it harder for Facebook to track your activity on other websites via third-party cookies.

Avoid trackers

By default, Firefox Enhanced Tracking Protection blocks cookies from known third party trackers and denies storage access to third-party tracking content, based on lists of tracking domains by Disconnect.
