yes, but i can have addon that will clean that cookie everytime i leave that sit and that cookie is only relevant for that site that set it.. i also can disable third party cookie at all so a site cannot see cookies for other sites.. and they can only track what sites you go that have their ad or their social media buttons.. afaik you cannot disable floc with an addon and you do not have any control over the floc id is assigned to you.. the floc id is calculated once a week based on the sites you visit on the previous 1 week.. so it leak information of what sites you have being visiting if anyone is able to reverse the sites that generated that floc id even if the site does not have adds or social media button on then or you use add blockers.. and i bet all the major tracking players will have farms calculating all possible floc ids from all the popular sites.. maybe do an addon that load randon stuff from randon domains in the background to taint the floc id so it makes harder to reverse the actual sites you are visiting.. or just use an browser that does not have it.. but beside floc, browser fingerprinting already allow tracker to identify people almost uniquely even without using cookies, there is already work on how to fingerprint someone without using either cookies or client side scripts, just by analyzing the timing when accessing several random subdomains using hundreds of redirects.. floc is just one more info they will have on you with no added benefit..
