The best thing about Firefox is Mozilla's Multi-Account Container tabs[0].
Essentially it allows you to put different tabs into different light-weight profiles, with their own session, cookies, and state. That means if you want to log into Facebook but don't want Facebook following you online, just give Facebook its own container.
Mozilla has anti-tracking already baked in, but Multi-Account Containers are a whole other level of isolation, but without sacrificing usability (like traditional multi-profile/multi-user browsing).
