I don't use wired headphones with my phone anymore since it doesn't have a 3.5mm jack, but I miss that i cannot plug my headphone quickly in a laptop's 3.5mm jack quickly.
I like that binary nature of cables. When physically connected they work. No fiddling with Bluetooth menus.
So what exactly are 3rd party cookies?
I'm on a.com, that is what's shown in the address bar.
The page includes a resource a.com/image.png. A request the server will include cookies from a.com. That's a 1st party cookie. Correct?
The page includes a resource b.com/image.png. The request will not include cookies from a.com; this was always the case. b.com can however set their own cookies. Since we are on a.com, cookies from b.com are 'third party'. Correct?
It gets interesting when we navigate to c.com and c.com includes b.com/image.png, a tracking pixel we have seen before on a.com.
Without 3rd party cookie protection, b.com sees the cookie they set previously while on a.com. This will now be blocked. Correct?
Now explain this in a Javascript world.
