Containers are a feature built into Firefox. There are extensions that let you use them more generally with any given website. It's also quite useful to log into websites with multiple accounts at the same time.
However, to prevent tracking I mostly use CookieAutoDelete [0] which only stores Cookies for sites that I have whitelisted after the tab is closed. It's really just a handful of sites I visit frequently and don't want to log in every time. Cookies aren't required for anything else.
Also, not having a Google account comes in handy to prevent tracking by Google. My default search engine is DuckDuckGo.
