Firefox, Brave and Safari do. Chrome and Edge do not.

That’s not fully protect you. They still can match short living third party identifiers with their domain cookie or device_id from app. It is not 1-1 matching but works relatively good with modern itp.

Not an accurate summary. That link actually says:

> Google Chrome doesn't block third-party cookies by default, only in Incognito mode, or when users explicitly set it to block third-party cookies via chrome://settings.

Looks like the settings let you block all third-party cookies and add exceptions for specific sites, which seems a bit awkward but could be made to work.

Alternatively, you could run OpenAI in its own profile, or look into what extensions might do.

		>Looks like the settings let you block all third-party cookies and add exceptions for specific sites, which seems a bit awkward but could be made to work. The fear over blocking third party cookies breaking stuff is severely overstated. I have it disabled by default and I don't think I've ever seen any website breakages. The most is office365 nagging me to click on links so it can authenticate across domains.

		I think that if they don’t block by default, is quite significant. Chrome + Edge has superior marketshare and then add the % people who have no idea what these mean and don’t change defaults.

		I was going to say, wasn't this supposed to be the default in Chrome by now? But Google reneged on it two years back: https://www.cbsnews.com/news/google-third-party-cookies-chro... This disgusts me more than any of their recent news. There needs to be a lot more pressure on them to phase this out. Maybe this article will be the small snowball that gets that started...
