What is First Party Isolation?
A concept from the Tor Browser, 'First Party Isolation' is a significant privacy measure. This Firefox add-on enables users to enhance their online privacy by keying every source of browser identification with the originating domain (first party), making all access to identifiers distinct between usage on the website itself and via third-party sources. In essence, it is a powerful alternative to blocking third-party cookies that works more comprehensively.
