To do this for all sites you can enable First Party Isolation if Firefox by toggling privacy.firstparty.isolate in about:config, or have a UI button that toggles is through an addon [1]. I've been using it for years and it only seems to break some payment processors, and only rarely.

Or at least not that I notice; I've been blocking all cookies, including first party, for a few months, using uMatrix. Obviously you need them for logins[1]. You need them on Twitter to view the old version of the site that doesn't require js. On YouTube, to view comments. To follow some redirects on the Android developer docs site. [1] ...mostly. Some actually store all the login info in js state (and presumably localstorage?).
